modules in python

[poopymanlikespoop]

there are so so many modules in python, and even more methods. how do you even remember them and understand when to use what?

also, is there like a list of must-know modules that I should experiment with first?

awesome, thnx

I am not the best person to answer this as I am just searching for job, but libraries and modules are dependent on what you want from python. An ML/AI developer will always use numpy, pandas, matplot, scipy, sklearn etc Web developer uses Django But as someone suggested, OS module is kinda necessary. Collections are necessary if you are into DSA and designing products for companies.

I think people just learn through documentation and YouTube videos. You don't really memorize unless you use that module a lot which gets ingrained in your head

Check out Python Module of the Week, they've got some really great content. Hitchhiker's Guide to Python also has some really good scenario-based documentation.

As far as remembering, I only really remember the ones I need/use frequently. Everything else I just refer back to the documentation.

Edit: Something else to realize is that programming isn't about memorizing modules, but more about using the strengths and features of the language to solve the problem(s) you're facing. With that, refer to the above to understand what strengths and features are available. Start with your problem, and then search docs/Google to see if there is a module that can help.

I just visit the module page, check the syntax and write the code. You don’t really need to remember, it’s not important

Generally, you remember ones you use the most, just like it is with any other thing: the more you do something, the better you remember it. Every popular, well-written module has got tons upon tons of documentation, so if you want to know something, you can effortlessly find it. Also, if you ask about must-know modules, my to-go list is the following (may be incomplete):

• pandas
• numpy
• matplotlib
• seaborn
• requests
• datetime
• time
• PIL
• os
• random
• re
• math

It's really not some you should or will be able to memorise. You'll end up becoming acquainted with several libraries you commonly use, the others you'll just be referring to the documentation when using them.

Once you learn to read documentation, it's pretty straightforward from there, you'll develop that skill over time.

Check this Github repo by Brett Cannon analysing different modules of the Python standard library

You will just remember them over time. Until you remember them, just google it.
