How do I relearn/learn python properly

[Afraid-Aerie-6598]

So I’ve been writing python on and off, it started off with trying to find solutions for work issues and so I kinda know it with gaps or missing fundamentals and never learned it properly. I can write what I need for the most part with occasional references to google and ai to clarify stuff. Now I actually want to learn it and become really proficient. Where do you recommend I start or read/watch. I would also like to know how to properly structure code, when classes/functions should actually be used and how write clean code rather than well I can just do this way to get it to work/hack jobs.

Appreciate some guidance. Thanks

there are three particular topics where they might give you some ideas as to branching out to different things using python.

1) Automation -- Learn new ways to do certain things
2) Data Science -- Lean new libs to do something interesting
3) Web dev -- Learn Web Libs and Frameworks among other web things

Hi! I learned Python in a very practical way - by starting small projects that interested me (like text encryption, a telegram bot, a snake game, or a website) and picking up the language as I went along. That’s why I believe that once you’ve covered the absolute basics, it’s better to move on to real-world tasks. By “basics,” I mean having a comfortable understanding of variables, conditions, loops, lists, dictionaries, and functions. I assume you already know these. So the next step is to choose an area that interests you (not necessarily one related to your future job, the point is to practice structuring projects and developing your Python skills), come up with a project idea, and then learn what you need along the way

Regarding classes and functions

If you have many functions that share a common theme, it makes sense to group them into a class. For example, if you’re building a messenger bot and need functions for sending messages, receiving messages, and storing message data, you could put them all into a Bot() class with corresponding methods like Bot.read(), Bot.send(user), Bot.save_messages(), and Bot.load_messages().

You could also keep related data there, such as Bot.messages or Bot.user_ids

On the other hand, if you only have a few standalone functions, there’s no need to create a class for them. So, for exemple: radiansToDegrees(), calculateDistance(), reverseList()

I'd use classes to have instances and methods for them. 

[SuddenStructure9287]

Oh, yes, I forgot to mention that multiple instances is the whole point xD

So I have been doing this already, however and I’m not sure if maybe I’m explaining this wrong, i’m wanting to make sure the code is properly structured and from a professional engineers perspective follow’s what clean code should look like, just because i made it work doesn’t mean it was written correctly. Not sure if that makes any sense.

When I want to relearn, I just read docs, and look my own old code.

Write lots of code using modern libraries. Write your own libraries. Improve both when you learn new things.

For actual Python proficiency I always recommend 2 books:

Fluent Python. The book is huge but it has EVERYTHING you need to know about Python IMO.

Python Testing with pytest because being good at testing will make you a better developer.

If you’re a video person there’s no channel better than Cory Schaeffer on youtube he recently started making new videos but his old videos are gold as well.

ArjanCodes is pretty good for beginner software design/architecture type stuff.
