  • Local variables: Defined inside a function and only accessible within that function.
  • Global variables: Defined outside any function and accessible throughout the entire script.
  • Nonlocal variables: Defined in an outer function and used in a nested function.

Example:

Copy Code 


global_var = 10  # Global variable

def outer_function():
    nonlocal_var = 20  # Nonlocal variable

    def inner_function():
        print(f"Nonlocal variable: {nonlocal_var}")
        print(f"Global variable: {global_var}")
        local_var = 30  # Local variable

    inner_function()

outer_function()
# Output:
# Nonlocal variable: 20
# Global variable: 10
