OpenCV & Python
OpenCV is the goto library for many image and video projects in Python, I remember struggling a bit with the documentation when starting out, so here’s a guided coding tour that I hope helps you.
Install OpenCV: <= Search for your particular environment, but this usually works:pip install opencv-python
What is it ?
OpenCV is a lot of things mostly dealing with processing images and video on your computer, my current interests are AI and real time applications, so this is biased towards that; for starters let’s look at simply capturing video from your webcam :

The result should be a video feed with the default OpenCV UI:
