Python NumPy For Your Grandma

NumPy, Explained So It Actually Makes Sense

Despite the playful title, this is a genuine NumPy course covering everything from installation and imports through to more complex problems involving array creation, transformations, and random sampling.

The format is on-demand, lecture-style video with animated examples, code walkthroughs, and challenge problems to test what's been learned, structured so students can move as fast or slow as they need.

The Approach

The course leans deliberately on understanding NumPy's logic rather than memorizing syntax, which matters for a library whose array operations can otherwise feel arbitrary. That emphasis on the reasoning behind array broadcasting and vectorized operations sets it apart from a plain function-by-function reference, and it's aimed at all levels, useful both as a first introduction and as a refresher for anyone who's used NumPy without ever quite feeling confident with it.
