Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

But several projects refuse to ditch all that ... A number of scientific packages for Python, such as Scikit-learn, draw on Cython features like this to keep operations lean and fast.

[Rossum] created Python as a hobby project over the 1989 Christmas holiday. He wanted a language that would appeal to Unix/C hackers. I’d say he was pretty successful in that endeavor.
