How do I use yield in Python?

In Python, 'yield' is used in a function to make it a generator. It allows you to return values one at a time, pausing the function's state.

Can you give me an example of a generator using yield?

Sure! Here's a simple example:

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

This generator will yield numbers from 1 to n.

How do I call this generator function?

You can call it like this:

for number in count_up_to(5):
    print(number)

This will print numbers 1 through 5.

What happens if I call the generator function multiple times?

Each time you call the generator function, it creates a new generator object. They can be used independently.
