What are some examples of variable scope in Python?

In Python, variable scope refers to the region of the code where a variable is accessible. There are four main types: local, enclosing, global, and built-in.

Can you give me an example of a local variable?

Sure! A local variable is defined within a function and can only be accessed inside that function. For example:

def my_function():
    local_var = 10
    print(local_var)
my_function()  # This will print 10

What about global variables?

Global variables are defined outside of any function and can be accessed anywhere in the code. For example:

global_var = 20

def another_function():
    print(global_var)

another_function()  # This will print 20

How do enclosing variables work?

Enclosing variables are found in nested functions. They are defined in the outer function and can be accessed by the inner function. Here's an example:

def outer_function():
    enclosing_var = 30
    
    def inner_function():
        print(enclosing_var)
    inner_function()  # This will print 30
outer_function()
