This post shows you how to use arrays in Python and why this data structure is so useful. A foundational skill for data science, coding, and more!

Using NumPy for array and matrix math in Python Many mathematical operations, especially in machine learning or data science, involve working with matrixes, or lists of numbers.

Here’s how to use Cython to accelerate array iterations in NumPy. NumPy gives Python users a wickedly fast library for working with data in matrixes.

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 ...

Microsoft's two new video series target beginner developers interested in using Python for machine-learning programs.
