I switched from js to python to solve leetcode problems(which was great). It ain't that hard. You just need to learn how to use data structures. You don't need any tutorial/course/book for that. Just follow these process: 1)Start by solving easy problems that require minimalistic code 2)Ask from chat gpt about how to do certain python operation(such as creating array, popping element from stack) 3)If you get syntax error, ask again it from chatgpt about this issue 4)After solving problem, look at solutions, and learn how other people solved it.

r/leetcode on Reddit: Switching from Javascript to Python in order to grind Leetcode, what’s the best resource to learn the intricacies of the language?

November 24, 2023 -

I’ve been working as web dev for a few years, all JS/React based. Now I’m starting to learn DS&A and do Leetcode and I’m realizing that I’m not doing myself any favors trying to stick with JS when solving these challenges, so I decided to learn Python.

All the Python courses I see are about learning to program from scratch. I’m not interested with that, I just wanna familiarize myself with the syntax and understand how it’s different from JS.

Is there any Python course as a 2nd language? Meaning that’s tailored for already experienced programmers?

Any advice for someone in my particular situation?

Well you should go to javatpoint website they have python section try to skim over that see if you can get familiarized with the syntax. Also go to hacckerrank python they have structured it from basics to advanced so you can practice

Why JavaScript is actually a great LeetCode/Interview language - DEV Community

September 23, 2020 - C++ has a bit more convolution with memory management and iterators, but trades that for speed. Java is notoriously verbose, which is often against the spirit of fast iteration during interviews. On the other hand, people often like Python since it's similar to writing pseudocode, it has a super beginner friendly community, and is fast to iterate upon. I'm going to present some reasons (in no particular order) why JavaScript might be the best of both worlds for coding challenges (but especially as an alternative to Python).

r/leetcode on Reddit: Thoughts on using Javascript for Leetcode questions?

August 6, 2022 -

I'm a full stack web developer in Javascript with about 3 YOE and I'm trying to switch to big tech or a fortune 500 company.

I recently started LeetCode prep and been using JS as my primary language since I have the most experience with it. However, I noticed a lot of the LeetCode solutions in the discussions (especially the top ones) rarely use Javascript. The common languages I've seen are Python and Java. I'm wondering if these questions could be solved more concisely using Python or Java especially since Javascript lacks
some built in data structures (e.g. stacks, queue).

I'm thinking of switching to Python or Java. I had experiences with both in university, so I just need to brush up on them. However, I'm not sure if it's bad practice to use a programming language that you've never used in professional work or personal projects. Also, I'm not familiar with the expectations around this especially in big tech companies with DS/algo focused questions as opposed to domain focused interview questions. What have your experiences been on the expectations around this?

No it doesn't matter if you use Python or Java, in fact I recommend it. Most people will know how to read Python, but not always JavaScript. I made the switch because it can make it easier for me to solve problems, it's basically always accepted in interviews, most interviewers know how to read it, and when I'm watching videos a lot of them are in Python

I used to do Node (200+ LC solved with it) but switched to Python, and recommend you do the same. You'll notice no MANGA+ interviewers do Node so you'll be in an unnecessarily weird spot. There's also quirks with Node that bite you, and lots of tricks with Python you'll come across that make your LC life easier.

It is only syntax difference. But if your day to day job is not related to python and you are looking for front end roles. Use JS. Otherwise, if you open to backend, python could be useful in the future.

JavaScript doesn’t have a heap library. You need to write your own that’s the only downside I can think of.

r/leetcode on Reddit: Age old question of which language(Js or Python) to pick but with some added context

August 18, 2023 -

Hi I have been learning HTML+css+js for some months now via Odin project.

I am nearing the end so I am doing personal projects.

In my current one I have come across json files which has array of objects with size/length 10k and I have to deal with this data. So I decided to start DSA.

Now in my head once you get the concept the language shouldn't matter but I have seen a lot of times Python being recommended to even webdevs. Is it just for interview process? because I feel like using it for my case I need to do it in Js.

So which approach is better?

eventually do I need to do it in both?

Or

doing basic DSA in both Js and Python. Plus leetcode practice in python.

If you know how to do it in Python, you will know how to do it in JS/C++/Java whatever. It just takes some time to translate idea from 1 language to another. The main focus of DSA is to come up with idea itself in the first place. That's why language doesn't matter much. The reason why Python is recommended over JS is because it has a lot of built in data structures so you don't have to implement them as you solve.

What is basic DSA? Leetcode is DSA. If you wanna be a JS dev use JS. If you wanna be a python dev use python, for DSA as well. Don't overcomplicate it.

I have done around 200 problems on leetcode using Java. At work I also use Java. I would say that I’m proficient in it.

However, I would like to transition more into ML roles, and therefore I would like to learn more Python

I would like to start a year plan in which to prepare for interviews and do leetcode problems and I was wondering what are you guys think if I should switch to python for the code problems even though at first it will be much slower, as I still gotta learn some syntax?

Is there really a benefit of using python versus Java?

Yes. It will take like a week to get comfortable in python. I solved like 100 problems in Java before switching to python. You save like 5 mins just by having less code to type and you don’t have to remember lot of boiler plate code

Leetcode python is very different from ML python. Can confirm cause I work in ML and do leetcode in python. Do leetcode in whichever language you are the most comfortable with. Think of it like you have to speak your logic out. I'm sure you'd best talk in your native language right?

The Best Programming Languages for LeetCode — PIRATE KING

September 25, 2023 - It's probably the most efficient and optimized language for coding interviews! Another important reason to choose Python over others is the built-in libraries. For example, some languages don't have PriorityQueues built-in. Aside from LeetCode, Python is frankly the most attractive programming language nowadays.

October 30, 2023 -

I'm starting my Leetcode journey but I don't know Python. I don't really have time to learn a new language for various reasons but especially because I'm currently working a full-time job.

Are there any time complexities in JS that are worse than Python that would prevent me from passing an interview compared to someone who uses Python during their interview? Sorry if this is a newbie question but I don't really know much about Python. Thanks

I would use the language you are most comfortable in. JS is fine, I don’t think Python is inherently faster to write than most other languages. Also your confusing time complexity with runtime. Time complexity is how the time it takes your program to run scales with the size of the inputs, it’s independent of language choice. As for runtime I would say JS is generally faster than Python but for an interview I wouldn’t worry about this at all.

Not at all. There is no reason python would be faster than JS since they're both interpreted languages.

python is just very convenient for leetcode, it comes with so much that's either included or is one import away that it simplifies most problems a fair bit.

I use TypeScript (basically JS) for LC. I wouldn't worry too much about the language you use though. If you don't know a programming language, then python tends to be a good option because the syntax is simple and there are some automagical methods/syntax that make it ideal for translating concepts into code. But at the end of the day, LC type problems are 80% concept and 20% language. Not worth spending so much time learning a new language for the sake of solving LC.
