r/Python on Reddit: How long would it take to learn Python for an experienced programmer?
December 25, 2019 -
I've been doing full stack Javascript for a while, I also know C# and C++. I know Python basics from having looked at code etc, after all its very readable but haven't done much coding.
I'll be honest, my current work doesn't really have Python projects, and I really want to learn because 1) its a good thing and I'm sure I will find uses for it, but mainly 2) I want to use it for technical coding interviews.
I really don't want to use C++, C# or god forbid Java (the opposite of terse). In the past I've used ES6 also and its generally fine but some companies have the impression that its not a 'real' language (which is nonsense). Anyway Python is even more terse/readable (well except for lambdas) and has more data structs (like queues, heaps) that are often used in interviews.
Just to make it clear, I'm not trying to 'cheat' or memorize. I want to learn the language but with a focus on solving questions like you see in leetcode vs e.g doing ML or data science. Things like list comprehensions etc seem very useful. JS ES6 and Python seem very similar in many ways so I think this will come down to really understanding the 'Pythonic' way of doing things after learning the syntax etc.

How long it takes is going to vary depending on the person and how much time they spend each day on learning it. If you spend at least a few hours a day trying to learn it than you could probably reach an intermediate level of knowledge in a month or so. Its probably going to be mostly just learning the differences in syntax, but Python definitely has some abnormal quirks that will take awhile to get used to coming from other languages.

I am used to the C++ standard and it takes me full weekends to study a single topics. I was able to read the full Python Standard in a day and there was enough time to go over some parts multiple times to make sure i got the important parts, it was surprising to me how small of a language python is. So i'd say you can get started in a weekend and with some practice you'll be efficient a few days later (especally with a good editor, syntax highlighting and code completion). Getting deep into a few of the many existing python libraries (like numpy, pytorch, ...) will probably take longer than learning python. And you will have to learn a few of them, because most python code relies heavily on additional libraries (Python Modules).

Learn JS then Node. Node won't make any sense until you know the language.
javascript.info will cover just about everything related to JS
MDN for deeper dive into the various APIs
Node.js is a run time built on the V8 engine. You won't be able to "learn" it overnight. Wes Bos, Steven Girder, etc. all have good intro courses to help you get familiar with the environment if you're a new learner.

I’m going the ofher way, learning python from scratch as a snr. js stack dev. Don’t mind python but there’s quirks to every language. I generally don’t find the tooling as satisfying in python yet, but I do like the fluency of the language. I like that I write it once and can expect it to do what I think it’s gonna do. I’m also not yet used to indentation mattering as much, not a huge fan but again; quirk of the language. Tips I’d give python devs learning JS: stay the hell away from frameworks until you’re comfortable with the core language, learn es6/typescript. learn by doing, find a project and work out how to spin it up, then find flaws and see what JS has to offer to improve in those areas. you’ll never learn it all, stick to making stuff that works/solves your problem. learn about javascript’s weird and predicable but not expected scoping rules pick up a typed form of JS (typescript/es6 with types) set up eslint with recommended(s) and prettier so you get the style of pretty-good js. learn the es6 way of doing something before the library-laden way. (Like the pyhonic way but for js) spend time on closures, async/await, lambdas, scoping, destructuring and Promise patterns (all, race, allResolved, etc), oh and coercion. look at what your ts/es6 transpiles down to (unminified) to get an idea of how JS does stuff under the hood. learn about tooling (node, npm, nps, jest, nyc, eslint, prettier, webpack/a bundler) learn about number/decimal handling if you plan on doing any math you need to trust (financial), see decimal.js & similar. Run “0.1 + 0.2” if you’re not sure why. learn about all the crazy places you can deploy JS (browser, node, electron, capcitor, etc). If you’re picking a base framework for front-end dev the answer is probably react. The State of JS survey results can guide you on what frameworks and libraries might be worth picking up. Good luck and welcome to ordered chaos.

I wonder how long it takes to learn Javascript (enough to pass jobs interviews) if I study it 3 hours per day and I'd like to know what frameworks should I focus on for better career prospects.
Thanks you!

Modern JavaScript and Python have a lot in common - for example the iteration protocol, generators, module import syntax, and async/await syntax should feel pretty similar. JS does not have comprehension syntax (e.g. the list, dictionary, set, and generator comprehensions available in Python). It is much more common to use functional programming patterns. Arrow functions in JS are analogous to lambdas in python. JS functions do not have keyword arguments. Instead, it is fairly common for functions to accept an "options" object as their final positional parameter, containing key-value pairs. JS does not differentiate between "items" and "attributes". They are all just properties on an object, accessed with either square brackets obj['propertyName'] or dot notation obj.propertyName. A JS object literal is kind of similar to a dictionary in python, but JS also now has Map and Set classes. JS has a contextual this keyword, instead of a conventionally-named self parameter for object methods. Methods are not auto-bound to objects like they are in python. The this keyword is provided to a method at call-time - for example if you call someObj.someMethod() or someObj['someMethod']() the dot notation and square bracket notation implicitly provides someObj as the value of this inside someMethod. However in the following code: let method = someObj.someMethod; method(); The this keyword will not be someObj - it will either be the global object or undefined depending on if you are using strict mode. Function objects also have call, apply, and bind methods which can be used to explicitly set the value of this. JS does not have magic methods like python has - so you can't override the behavior of builtin operators like you can in python. For example the === operator always compares values by strict equality (same type and value for primitives, referential equality for objects). JS classes do not support multiple inheritance, though multiple inheritance is possible via object prototypes. JS has a for...in loop as well as a for...of loop. The for...of loop is the one that works like for...in in python, which is easy to mix up. JS has both a null primitive and an undefined primitive, as opposed to Python's singular None. Obviously there are syntax differences - python uses a much more minimalist, significant-whitespace syntax, while JS has a more C-like syntax with more brackets, parens, semicolons, etc. And of course there are various other differences, but these are the ones that I think are most likely to trip you up when learning JS coming from a Python background.

I mean... it's different for different people, but if you know Python you should be able to pick up js relatively quickly. Maybe a couple months then start applying to jobs? React is probably still the biggest framework and best for job prospects.

I'd vote Python first unless you need to get up to speed quickly with JS. Or maybe if you have a web front-end that you can't wait to start building right now. Python has very clean syntax and it's a very coherent language. It's great for writing small scripts, which is mainly what you'll be doing as a beginner. It's also handy in that it can interact with your OS in ways that JS (in the browser) can't. JS has a slightly more complicated syntax. But it's also got a lot of warts and weirdness. I learned a language very similar to JS as my first programming language. It was ok. Not the end of the world. But I'm glad I learned other languages afterwards.

Is python similar to javascript will I be able to pick up everything fairly quickly? I have been learning python for a couple of weeks now and I'm slowly gaining an understanding. I plan on sticking to learning html, css and python for a month or two more than try and learn some javascript and react, I actually first started on js but skimmed through html, css quickly and then javascript hit me pretty hard then life got in the way. So I started with python one year later and feel much better, perhaps my original approach was poor. Also eventually I was thinking about full stack so thats why I thought python was quite a good choice for back end.
Thank You.

There are some similarities between Python and Javascript. However, Javascript is much more about the web. So it won't be completely automatic to switch esp. because you have more web concepts to learn in Javascript which you don't need in Python. It does help to learn a second language once you learn a first language, depending on how close the two languages are. Usually, the second language is something of a challenge. If I had to give a number, I might say 6 months to learn Javascript. React is the harder part, I think. They say it's better to be pretty solid in Javascript before you do React instead of jumping directly into React. This is based on what I've read, but I've done only a little Javascript and really no React at all.
