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 local scope?

Sure! A variable defined inside a function is in local scope. For example:

def my_function():
    x = 10  # x is local to my_function
    print(x)
my_function()  # This will print 10

What about global scope?

A variable defined outside of any function is in global scope. For example:

y = 5  # y is global

def another_function():
    print(y)  # This will print 5
another_function()

Can you explain enclosing scope?

Enclosing scope occurs in nested functions. A variable in the outer function can be accessed by the inner function. For example:

def outer_function():
    z = 20  # z is in enclosing scope
    def inner_function():
        print(z)
    inner_function()  # This will print 20
outer_function()
