Python follows the LEGB rule (Local, Enclosing, Global, Built-in).
When you reference a variable, Python checks in this order:
-
Local – variables inside the current function
-
Enclosing – variables in outer functions (nested functions)
-
Global – variables at the top level of the script
-
Built-in – Python’s built-in names
This resolution process is essential for beginners who want to Learn Python Online, as understanding LEGB helps you write cleaner, bug-free code. The first match determines the scope.
