What are Python decorators and generators?

Can you explain what Python decorators are?

Sure! Python decorators are functions that modify the behavior of another function. They are often used to add functionality to existing code.

How do I create a simple decorator?

To create a simple decorator, define a function that takes another function as an argument, and then define a nested function that adds the desired behavior.

What about generators? How are they different from decorators?

Generators are a type of iterable, like lists or tuples, but they generate values on the fly using the 'yield' keyword. Unlike decorators, they are used for creating iterators.

Can you give me an example of a generator?

Certainly! Here's a simple generator that yields numbers from 1 to 5:

def count_up_to(n):
    count = 1
    while count <= n:
        yield count
        count += 1
