[DISCUSSION] What's your favorite Python library, and how has it helped you in your projects?

• Toolz

  23 4,665 4.6 Python

  A functional standard library for Python.

  

  My favourite lib would probably be toolz, it's just so elegant and fun to use. But it's more functional approach is not always the best fit for the time, so in practice I mostly use it in research, prototyping, console and notebooks.

• pydantic

  174 20,746 9.8 Python

  Data validation using Python type hints

  

  As for the most utilized and still loved library, that would probably be pydantic, it helps declaring types so convenient - be it dto's, models or just complex arguments - and plays nice with bunch of other libraries from it's own ecosystem.
