What are functions and scope in Python?

What are functions in Python?

Functions in Python are reusable blocks of code that perform a specific task. They help organize code and improve readability.

Can you explain the concept of scope in Python?

Scope refers to the visibility of variables in different parts of your code. In Python, there are local, enclosing, global, and built-in scopes.

How do local and global variables differ?

Local variables are defined within a function and can only be accessed there, while global variables are defined outside any function and can be accessed anywhere in the code.

Can you give an example of a function with a local variable?

Sure! Here's a simple example:

def greet():
    name = 'Alice'  # local variable
    print(f'Hello, {name}!')

In this case, name is a local variable.
