What are scope variables in Python?

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

Can you explain local and global scope with examples?

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

def my_function():
    local_var = 5
    print(local_var)
my_function()  # This will print 5
print(local_var)  # This will raise an error

A global variable is defined outside any function and can be accessed anywhere in the code. For example:

global_var = 10

def another_function():
    print(global_var)

another_function()  # This will print 10

What about enclosing scope?

Enclosing scope refers to the scope of a function that is nested within another function. Variables in the outer function can be accessed by the inner function. Here's an example:

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