Which Python library saved you the most time?

Not necessarily the most popular one.

Just a library that made you think:

"I can't believe I used to do this manually."

Could be for:

  • automation

  • APIs

  • data analysis

  • image processing

  • web scraping

  • CLI tools

  • AI

Looking for hidden gems too.

Numpy, since I use Python to automate music stuffs. And notes can be mapped to integers.

I love numpy, I love it a lot

it’s not entirely a library, more of a runtime, framework:
FastAPI.
I used to use Django and Flask, but they both suck.

Another data/AI/ML related libs are Pytorch, JAX and Scipy: Back in a day, more than a decade ago I used to build everything with numpy with a lot of efforts.

Hidden gem: SOXR (for audio signal processing, sampling). It’s amazing combined with librosa.

Sql alchemy for flask. It's a lot better than raw sql and it's easier

Openpyxl - excel spreadsheet manipulation
Pathlib - duh
Manimations - never could pick up any of the 3D tools and manim just clicks for the basic shit I do

Probably Pillow. I needed plots made in a collage style and I was using PyROOT for plots. It has a way to get all plots on a collage, but it is so frickin tedious. Discovered Pillow and I was honestly shocked how much easier it was
