r/learnpython on Reddit: Java after python.. possible??

August 8, 2022 -

I have been learning python for a year and I think I can code in python! I just need to work on projects to advance my skills. Lately I have been thinking to learn Java...so I took advice from my friends. They said I will have tough time learning Java because I have learned python before. They said I should have learned Java first and python later... maybe I messed up 😅😅

Is it true? Will it really be that difficult?😩

Python is my first language and I am thinking of learning Java now. Can I?! Please share your opinions

Thanks in advance 🤗🤗

No, learning any programming language before Java will make learning Java easier.

You will be shocked at how fast you pick up Java basics if you know Python. I had spent about 150-200 hours learning/coding Python and recently made the switch to Java for school. When people say learning a second language is much easier than the first, they are really not kidding! Do MOOCs Java course. Best of luck on your journey!

r/learnpython on Reddit: Learning python with java knowledge

February 17, 2025 -

I am currently attempting to speed learn python because I need it for a shadowing opportunity that I have tmr. I have java knowledge, and I know basic Python. Does anyone have any tips or resources that I can use?

Here's something I wrote a while back for devs coming from languages like c/c++: Python is just another coding language, so existing skills in programming and domain knowledge will benefit potential employers/clients even if they require Python coding. Experienced programmers know that coding is a small part of programming, but proficiency in (and enjoyment of) any particular language, best suited to particular problem types, is, of course, highly beneficial. There are many areas that Python has become well established in. Machine learning and AI are very well served in Python. Alongside R for the more statistically inclined, data science & analytics is an incredibly common field for Python. The latest release of Excel includes Python in recognition of this. A review of Python Success Stories , on the Python Software Foundation website, will provide a good view of the wide range of areas Python has been used in. Python isn't the best answer for all problems (and may be highly unsuitable for some, of course), although it might be the most pragmatic in organisations that have a lot of experience in, and well established ecosystems around, it (such as sophisticated CI/CD pipelines). For example, Python isn't the best language for modern triple-A games, but it is heavily used by many games software houses to orchestrate, automate, optimise the work. Some of the largest consumer services in the world are heavily Python based, such as Instagram (leaning strongly on the Python Django web framework). Most experienced programmers shall be well versed in data structures, algorithms, design patterns, and so on. They are largely independent of the coding language. The same principles apply to Python, although the implementation patterns (and efficiencies) will vary. Similarly, successful programmers will likely be comfortable with CI/CD tooling and workflows, which are just as important for Python as for other languages. Programmers new to Python may want to spend some time looking at the most popular testing frameworks, though, such as PyTest (rather than the standard unittest) to work with those pipelines. Packaging for Python is perhaps another area to get some experience around as that will be different from other languages, especially given that as standard Python is not compiled to binary. (for those not aware, the standard CPython reference implementation compiles to byte code, much like happens with Java, for execution in a Python Virtual Machine, built into CPython.) I'd recommend looking at videos on YouTube by ArjanCodes , especially those doing some kind of code reviews (will help you spot a lot of potential problems). One book I would recommend is Fluent Python, 2nd Edition by Luciano Ramalho. ADDITIONAL CONTENT IN COMMENT TO THIS COMMENT

Learn about generators and yield. If you have time learn about iterators, they're everywhere in Python. And Dunder methods.

r/learnprogramming on Reddit: As a complete beginner what should I start with Python or Java?

July 2, 2024 -

I am about to join college in 1 month and will be starting my coding journey. On most youtube videos people say that beginners should start with either java or python.

I like Ai stuff and that is mostly done by python (acc to what I found on the internet) but then Java is for mostly opensource and development( again acc to internet). Open source and development seems like more leaning towards better placements but then python seems easy and most Ai and ml is going on python.

I'm very confused right now, I wanna be able to build some good stuff with either language, but starting out is just overwhelming. No idea where to start.

Edit 1: I have kind of decided to start with Java and my college with probably start with C language so I'll try that in the 1 month I have left.

While you'll certainly find opposing opinions on this subject, realistically (unless you have a certain goal in mind) it doesn't really matter that much. Both have been used successfully as a first language by universities and self-taught programmers. So there are no wrong choices here. You won't be affected negatively by either choice. You'll probably end up learning both anyway. Most professional programmers know several. That being said, there are two things you said that could better inform your choice: I am about to join college in 1 month Check and see what language you'll be learning in college. It wouldn't be a bad idea to get an academic head start (to make things easier for yourself) and start learning that language earlier. I like Ai stuff and that is mostly done by python It's true that the majority of AI work is done using Python, so it wouldn't be a bad idea either to learn Python for AI stuff.

As a student on his first year, I'll recommend java because it's OOP. Python just seems too easy compared to the "slight" complexity you have to learn from using java. Another reason why I recommend java is because it's very similar to c# (syntax wise), which is so fun to use. Learn one, and you will know the other. If Ai is your only goal then you will have to choose python.

r/learnprogramming on Reddit: Best way to learn Java (no videos or tutorials) for a python mid-level programmer?

September 22, 2022 -

Hi! I’ve been trying w3schools and Codeacademy but when I try to program it I get so many errors. How could I improve my learning?

I get so many errors. Honestly, even though you said "no videos or tutorials", you need one. Do the MOOC Java Programming from the University of Helsinki. Python and Java are very different beasts. You can be a decent programmer at either and will find the other difficult. Hence, do a course. I just recently started learning Python coming from a long history (>3 decades) of professional programming in multiple languages (Delphi, VB, C, Java, bit of C#) and still found that I absolutely need a structured course to get started. The gap between the languages was just too big. Sure, with the experience, you can breeze through the initial chapters as they deal with very basic things, like variables, conditionals, input/output, but you will still learn a lot. If you absolutely do not want to go that way, you need to learn to read and understand the errors and debug them. Yet, going this approach will make it way more tedious than it need be.

I highly recommend these two free online Java courses: MOOC.fi . The courses have you learn Java while simultaneously doing mini exercises to apply what you learned. The exercises get more complex as the course goes on. At the end of the second course you create a pretty decent GUI game. I skimmed your profile to gauge your level of Python. You'll probably find the first half of course 1 pretty easy, but everything after that will likely be mostly new to you. Course 2 will likely be all new to you. It's very easy to learn Python without really thinking about object oriented programming (OOP) concepts, but with Java you must learn object oriented programming concepts. After those two courses, I recommend doing a couple of small projects in Java and then reading a book on OOP design patterns. I recommend a called book "Head First Design Patterns". After that you should have a very solid understanding of Java and OOP fundamentals.

r/learnpython on Reddit: Java programmer learning python?

April 4, 2025 -

When I was in college, I got my CS degree when the primary language being taught was Java. I am fairly comfortable with Java as a language, but I left the field in 2010. Now it seems like Python is the preferred language, so I am attempting to learn it to hopefully find some sort of part time work.

I am curious where the best place to start would be. I have looked up projects to learn python online, but many seem focused on teaching basics of programming and algorithms and such, which I don't really need given my background. I want to learn the ins and outs and specifics of python as a language.

Any advice?

As a former C++ programmer here are the things that worked for me: The official python tutorial: https://docs.python.org/3/tutorial/index.html is enough to get you up and running quickly. I found "Learning Python: Powerful Object-Oriented Programming", by Mark Lutz to be useful for filling in the details. Comprehensive and in-depth. Practice: https://checkio.org/ was a useful source of small practice problems. It helped me to understand "pythonic" programming. A gamified set of programming problems. Easy enough to do while drinking a morning coffee. After you solve the problem, you get to see how others solved it. I enjoyed solving these problems. Other useful resources: https://docs.python.org/3/library/index.html - Covers the built-in functions, built-in datatypes and the standard library. https://pymotw.com/3/ Python 3 Module of the week. Demo code that shows how to use the standard libs. A nice addition to the reference documents.

The official docs are more than enough for a seasoned programmer. If you know Java, you can pick up python in a week or two.

r/learnpython on Reddit: Is it bullshit: Know Java, easy to learn Python. But not the other way around.

August 11, 2019 -

Hello people, I am looking to learn a programming language during the summer before college. The classes I'll be taking at univerisity uses Java. However, I've been trying to learn Python on my own for around two weeks using Automate the Boring stuff and Code academy. So I am still a noob. However, I've read some posts where people say learning Java as a first language will be much better than learning Python as a first language because it is easier to transfer from Java to Python but not the other way around. Now I am conflicted in which language I should devote myself to for the rest of the summer. Please give some advice. Thanks!

Edit: Thanks to everyone who replied and who tried to help. So some said that Python allows you to skip the useless code which therefore allows you to focus more on the concepts. While some said that Java forces you to explicitly write out all the steps which teaches you more on the fundamentals. Although I will eventually be learning Python as I am interested in Machine Learning/AI I think I will be learning Java for the rest of summer until university starts simply because of the fact my classes uses Java so I was think about getting a slight head start. Once again, thank you to everyone who helped.

However, I've read some posts where people say learning Java as a first language will be much better than learning Python as a first language because it is easier to transfer from Java to Python but not the other way around. It's easier going from Java to Python because Java contains a lot of useless boilerplate code that you can skip in Python. But that doesn't make Java a better first language, as that boilerplate code is exactly what will waste all your time and confuse you when you are getting into programming. Python makes a nice first language exactly because it allows you to focus on the high level programming concepts. Case in point, Hello World in Python: print("Hello, World") Hello World in Java: public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World"); } }

Java will teach you more about programming fundamentals because Python is designed from the ground up to eliminate as much scut work and boilerplate as possible from common programming tasks while java (and most other languages) force you to explicitly cover all of the steps.

r/Python on Reddit: How does an experienced Java developer pick up Python?

July 1, 2018 -

Hello guys, I need some suggestions to learn Python. Recently My boss assign a Django-based project to me. But the problem is I don't have any experience in Python. I tried to follow documentation and tutorial on the Python official website.

I found it is not easy to learn Python when I have experience in java for several years.Because Java has a very strict typing and concepts that are general solutions to any complex problem.

Python tend to abstract these concepts and allow code that might be better at readability, but this comes at the cost of not having good IDE support and more importantly is more prone to error.

What are some recommended learning methods I should follow?

learning new paradigms and writing idiomatically in another language will make you a better developer overall. you should look forward to this opportunity rather than fretting it

sloppy coding is what leads to errors, not the language. just relax, be pragmatic, and you'll be fine. millions of people use python without issue. there's nothing to worry about

as far as IDE support goes, pick up pycharm (or if you already use intellij, install the python plugin) or visual studio. use type hints, and though not as solid as for a typed language, it takes you pretty far

this is a bit old, but it's a good starter: https://dirtsimple.org/2004/12/python-is-not-java.html

dont skip this: http://docs.python-guide.org/en/latest/writing/gotchas/

Hi there. I'm currently a Java Developer with 3 years experience and I'm wanting to move to Python instead. Where would be a good place to start? I have "Learn Python the Hard Way" and I'm currently reading through it

Essential reading IMHO Python Is Not Java and Java is not Python, either... . I got into Python myself via the highly recommended Dive Into Python 3 .

Lpthw is for complete newbies, don't waste your time on it. Automate the boring stuff is good. I'd recommend taking simple programs you wrote in the past and porting them to python.

Hi everyone, so as long as I know, Python is an easier language to start learning programming, however, I might have a greater oportunity of getting a kind of internship or even (long term goal, crossing fingers) a job at a company that works with Java because of connections.

What is your experience?

You just need to learn programming, if Java in your network is used more then start with Java.

Go with Java. If that’s what the job your connection can get you then learn that. You can learn Python later. That said, this whole programming BS is problem solving. Being “fluent” in a language doesn’t mean you trained to problem solve.

I will just be to the point, I just find it fun to learn how to code and want to be able to independent create code create things without error. There’s an interval between where I learn hello world then language I don’t understand. It’s very small and I don’t know where. Is it all important to learn?

I think learning Java first will make you a better programmer in the long run. Python will be simple to pick up after some Java mastery

Java's awesome for diving deep into coding logic and building stuff like Android apps. It’s a bit tough at the start but super powerful. Python? It’s easier to get into and super versatile, great for web stuff, data science, and even AI.

r/learnprogramming on Reddit: Is it true I should learn Python before Java from the start or can I jump right in with Java?

July 22, 2018 -

Just curious because I want to start to learn how to build applications most specifically for mobile and Java seems to be the best language to go about this for Android. However I've seen people say you should learn Python first

Of course you can jump right in. People say to learn python as your first language, but that’s assuming you’re going to learn more and more afterwards and don’t have one in mind. Python is a good introductory language, but if you are more interested in Java it would be a massive waste of time to learn python first. Of course it’s good to know as many languages as possible but if you want to get started with java based projects don’t waste months learning a different language, learn java first and go from there. People recommend python as a good first language but really it doesn’t matter which you learn first. Definitely learn java first imo.

You can learn whatever you want first.

October 30, 2018 -

After December we will move away from Assembly at work (I work there as an apprentice and they want me to learn it, they don't actually use it). I get to choose between Java and Python. I will learn the other one later anyway, but in the beginning, which should I take? I work there as a Software developer with only very little pre knowledge.

Python is more like a handy swiss army knife Java is full blown war Tank. I would prefer java.

I had a lot of luck learning the easier things like decision statements and loops with python, but learning OOP and some more complex things was a lot easier to understand with Java. Don’t think you need to learn just one, focus on the concepts!

What's the best way to learn Python individually if you know a bit of Java?

I'm studying software design, at the first semester, and have taken an introduction course to Java. The problem is that I have another elective course in the summer that requires Python, which our study programme won't teach us before.

Learning the python language with programming experience is extremely easy.

Learning to actually develop in python is a bit harder but if you’re in university you don’t know how to develop in any language yet so it doesn’t matter.

Don’t worry, you can pick it up as you go.

r/learnprogramming on Reddit: Should I learn Java or stick to Python?

August 24, 2019 -

I have been studying programming for the last six months. For the first four months I studied Python, and then I started studying studying data structures and algorithms. For data structures and algorithms, I picked the books where the code was written in Python. Now that I am about to finish that, I have decided to pick Algorithms by Robert Sedgewick. In this book all the code is written in Java.

I want to learn both Java and Python, and I will learn Java at some point. My question is whether I should start learning it right now or not? I know it's not necessary, but I think it will be much easier to follow the book if I have some understanding of Java.

Why am I confused?

Well, I have watched videos, read blogs about people recommending to stick to one language when starting out. So, I am scared to start a new language thinking I might forget Python or get into a situation where I don't understand either of these languages.

i always say programming is the skill, and the language is the tool. choose the right tool for the job. you can hammer in a nail with a screwdriver, but its gonna be a whole lot harder. also it doesnt help to learn how to use a hammer if you have a screw. important is that you learn how to work with your hands (aka aquire skill). algorithms and datastructures translate into any language, some make it easier, some make it harder, others already have ready made solutions or there are libraries.

r/learnjava on Reddit: Need to learn Java fast as a Python developer

April 30, 2019 -

I just started a new job last week and my task is to add a new feature to a complicated Java plugin. I haven’t coded in Java before... I am familiar with OOP but Python doesn’t really rely on it to the same extent as Java. I’d appreciate any resources geared towards experienced developers needing to pick this up fast, particularly focusing on the more esoteric/Javaesque (what’s the analog of Pythonic?) features as opposed to another one of the million “this is how you do a for loop in Java.”

For example, today I was banging my head because there was a function that took in a variable and did a bunch method calls to n the variable. The variable type was an interface and all the basic Java guides say you can’t instantiate an interface so I just didn’t get what’s going on until I understood that it means that any object type that implements the interface is permitted (what a terse way of saying that). So learning these kinds of features is especially valuable.

This is a good primer resource. https://learnxinyminutes.com/docs/java/

Make sure you set expectations with your boss that you need time to ramp up on Java to complete this task. Because you will need some time depending on the complexity of the plug-in and the feature

r/learnprogramming on Reddit: Professor said learn Python and Java. Why?

September 5, 2023 -

Hi all. I am a self taught learner of about 4 months now. In my last semester of school (business major), I took intro to programming and loved it. Really wished I did CS instead. I ended up emailing my professor from that class and asked what his thoughts were on self learning.

He told me to learn Python and Java and to have some kind of structure like an online course. Read the pragmatic programmer, and fluent python/effective Java.

I started with python and eventually found the Odin project and switch gears to js and web dev stuff. I am struggling to find a path and stick with it.

Why would my professor recommend those two languages to start with? Do these languages really relate to web dev? What kind of job opportunities can python and java lead to?

If you had asked your professor "what's the most common language for web frontend development," he'd've probably told you JavaScript. But there are lots of kinds of programming out there, and Java and Python are a pretty good choice for covering a whole lot of bases. Python's one of the most popular languages out there, especially for what's trendy today (machine learning) and for developing being done by professionals who aren't primarily programmers (scientists, analysts, business-folks, artists). Java's extremely popular for big corporations building lots of complicated little business logic services, and it's still fairly popular for web backends. Plus, there are huge amounts of "learn programming" resources aimed at both of those languages. Also: if you really want to be a professional developer, I might suggest hanging out for an extra year or two to get a CS minor or something if you can. If your plan is to study programming, and they teach programming where you are, why leave? But I also understand that staying in school longer isn't always possible, financially or otherwise.

CS professor here. The programming language you choose as a beginner is mostly irrelevant. Python is known as an easy language because its syntax is similar to written English. If you really learn how to program, you'll learn that the language is just a tool. Asking for the "best language" this early is like comparing screw drivers without looking at the screw. Some languages will do some things better, but you don't need to know any of that right now. When you learn how to make a loop in one language, you can do it in nearly any language with the smallest of effort. The hard part is learning how to do something, not how to write it. Go deep, not wide. The things you learn in one language can apply to other languages. Your professor gave you good info. Thank them and take the advice. P.s. I'd rather hire someone who knows one language really well vs. Someone who knows a dozen languages at a shallow level.

I'm taking an Intro to Python class at college next semester, and have been learning Java for 2 years. I was wondering how much I should prepare, and how difficult I could expect learning Python to be if I'm already pretty confident in Java? Thanks in advance.

You're going to have to unlearn a whole bunch of bullshit boilerplate.

OP, you shouldn't have any problems. If you can learn Java you can learn Python too; it's easier.

You could probably breeze through a beginner resource like this one and become familiar with Python in just a few days.
