# What are Python’s namespaces?

There are four types of namespaces used in Python programing.

1. **Built-in namespace** → functions like `len()`, `print()`.
2. **Global namespace** → variables in the main program.
3. **Local namespace** → variables inside a function.
4. **Enclosing namespace** → outer function variables in nested functions.

Remembering **LEGB Rule**: **Local** → **Enclosing** → **Global** → **Built-in.**
