i've been coding in java for a long time now, including DSA. but now for some reason i have to switch to python for a particular test. how do i go about it?

It isn't as hard as you might think. If you know java you know the core fundamentals of coding that are basically the same in every language. Once you know what you need to do, it's basically looking up syntax, libraries, etc. My advice is don't stress about it, take it slow. Python is actually pretty user friendly!

it would take as much time as you can find the official python docs site, assuming your background is as you say and you have can conceptually think through a problem. rest (syntax and other python specific things) you can handle as you go. i need to loop through the contents of a file and filter out lines that only have "#####". how do i loop in python? how do i open a file? how do i compare strings? how do i save a file? how do i save a file stream into variables? those things you can easily find in a syntax resource. you won't need to read the explanations.

Hi.
Basically I am not that interested in Java.
However, I need to understand algorithms, not just solve them.I read books, watched some things online, and even if i can explain some algorithm I can't code it.
I even had difficulties making a linked list in C.
I also lack the OOP understanding. I can read about it, solve quizzes but that is the thing i get most tripped about in Python.
Maybe it just my impatience as I found out I haven't exactly watched tutorials as I cant wait to get into it myself.
Maybe I should just bite the bullet and learn it exclusively for Sedgewicks algorithms.
To be honest i really like Python and see a future with it. Other languages aside from C have mostly been a derail and then I crawl back to Python and spend the next few weeks getting pythonic.
That's the thing, most other languages are idiomatic, but Python is pythonic. Maybe I've spoiled myself, trying to code in english?
I really want to understand classes and i heard Java is great for it too.
The only thing that puts me away is the syntax and the extreme opinion of the JVM, I don't want to spend a month relearning Python again.
To be honest at this point I would be really happy if someone said they followed Sedgewick just with python code from github or that the knowledge is transferable when watching lectures.
I tried with MIT and Standfords Roughgarden but it is very theoretical and at times very mathematical and far removed from code.
I get it i really do, that is what algorithms are. But for now I don't have the luxury of learning mathematics and relearning induction.
https://cs50.harvard.edu/ai/2023/
My goal for now is to be able to this and do it well and actually understand how it works.

To be honest, me, a C/C++ developer once had issues with grasping even such basic concept as pointers. You learnt Python and you enjoy it. That's good. You already have one language in your portfolio. Regarding OOP - if you use classes in Python it is already a part of OOP. (Of course, you need to be able to use e.g. inheritance in Python) You want to code in English, so you prefer something with easy syntax, so maybe JS? Regarding JVM - you should not care about it until you are senior-ish dev. Java philosophy is "run everywhere". If you screw up you JVM, it will just run slower and eat your RAM. ----- OK, I wrote a lot text, so let's summarize: Not being able to write a linked is not a big deal for a beginner You really must understand OOP. Without it you won't get your first job. You can do learn it in Python Btw, Python is not that great as the sole language, market-wise.

I started learning java through the Sololearn app on my phone. It meant I could learn java while out and about, while still focusing on my python projects when at home. Picking up Java this way made OOP finally click for me, and that in turn improv3d my Python code quite a lot.

November 18, 2020 - Functions with no return type are void in Java. Python functions have no return type but simply choose whether to include a return statement. The main method in Python is different from Java due to their difference in structure. main methods in Java are required to execute code while Python code will execute line by line.

It used to take me a day to go from a Factory to a full REST endpoint with Java, now it takes me a couple hours to model a basic CRUD application with Python and Flask.

A startup was using Java for their web application. They found that the development cycle was long and the deployment process was complex. After converting to Python with Flask, they were able to quickly iterate on new features and deploy changes more easily. Converting from Java to Python requires a shift in mindset, especially regarding type systems, design philosophies, and performance considerations.

Also, python prefers using lower ... than Java's camel case naming convention. (One is not better than the other-- just different.) The Python 3 code is slightly longer because it defaults to Unicode strings. Byte arrays -- when printed -- produce different output. Python 3.6 and later have the "fstrings" which make the print statements more compact. Hopefully this will help with efforts to convert code from java to ...

Switching from Java to Python – First Impressions | Henrik Warne's blog
June 22, 2014 - In Java, when I saw a new function and tried to understand what it did, I almost always looked at the types of the arguments and return value to get a sense of what it did. In Python, it is much harder. It takes a lot more digging to find out what a function does in Python. The quote from Linus Torvalds about the importance of data structures comes to mind.

All java-to-python devs I worked with are terrible python coders. The main issue is they never bother to really learn python, but assume they know everything because they can make some working code. So they're simply missing basic concepts, and are very defensive about it. Not only do they use classes everywhere, but then demand that everyone should write getters and setters (they never learned to use @property. They refuse to learn about Modules (and its impact on code structure, imports, architecture and design-patterns). And then they implement design patterns in java-esque ways, while Python often has different (simpler) alternatives. They keep saying __init__() is the constructor, and underscores are for private methods and dunder-methods are internals that you should not touch (all are wrong assumptions). It is really hard to un-learn things.

I'm going the opposite way - Python to Java. It's been a pretty steep learning curve. I miss the simplicity of Python.
