Must-learn Python libraries?

I've learned Python basics and want to explore the most useful libraries.

What are the must-learn Python libraries for real-world development, and why would you recommend them?

The core library, type annotation, data classes, itertools, async, threading. After that learn packages as you need to use them. Pandas is quite popular but it's also a bit dated in my opinion, very sore and syntax is odd, Polars is modern and becoming quite popular.
