What are the different types of parameter scopes in Python?

In Python, parameter scopes can be categorized into local, nonlocal, and global scopes. Local parameters are defined within a function and are only accessible there. Nonlocal parameters refer to variables in the nearest enclosing scope that is not global. Global parameters are defined at the top level of a script and can be accessed anywhere in the code.

Can you give me an example of local and global parameters?

Sure! Here's an example:

x = 10  # Global variable

def my_function():
    y = 5  # Local variable
    print('Local y:', y)
    print('Global x:', x)

my_function()
print('Global x outside:', x)

In this code, x is a global variable, while y is a local variable defined within my_function.

What happens if I try to access a local variable outside its function?

If you try to access a local variable outside its function, you'll get a NameError because the variable is not defined in that scope. For example:

def my_function():
    z = 15  # Local variable

my_function()
print(z)  # This will raise a NameError
