Indexing

Indexing

Indexing is a core part of NumPy. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding indexing well means you can read other people's NumPy code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What indexing means in the context of NumPy
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with indexing

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for indexing.
