Question

Explain LEGB rule.

Answer 1

The LEGB rule specifies the order in which Python searches for a name:

1. L - Local: Searches inside the current function.
2. E - Enclosing: Searches in enclosing functions, from inner to outer.
3. G - Global: Searches in the global namespace of the module.
4. B - Built-in: Searches in Python's built-in namespace.

Thus, Python uses the first matching name found in the order: Local → Enclosing → Global → Built-in.
