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!

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 ...

What is Python? This post answers that question and walks you through the basics. Set up a coding environment and build your first simple app!

Python uses zero-based array indexing. In most languages, Python and C included, the first element of an array is accessed with a zero—e.g., string[0] in Python for the first character in a string.
