What are the different parameter scopes in Python?

In Python, parameter scopes refer to the visibility and lifetime of variables. There are local, enclosing, global, and built-in scopes.

Can you explain local and global scopes with examples?

Sure! A local scope is created within a function, while a global scope is accessible throughout the module. For example:

x = 10  # Global scope

def my_function():
    y = 5  # Local scope
    print(x + y)

my_function()  # Outputs 15
print(y)  # Raises NameError

What about enclosing scope?

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

def outer_function():
    z = 20  # Enclosing scope
    def inner_function():
        print(z)
    inner_function()  # Outputs 20
outer_function()
