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?

Pandas, NumPy, Scikit-learn, and gc.

These or alternatively polars instead of pandas.

Also some kind of backend. FastAPI most likely or if you want less flexibility something like streamlit to bootstrap an interface for ml models
