How do I create a generator function in Python?

To create a generator function in Python, use the yield keyword. This allows the function to return values one at a time.

Can you show me a simple example?

Sure! Here's a simple generator function:

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

How do I use this generator?

You can use it like this:

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

This will print numbers from 1 to 5.

What are the advantages of using generator functions?

Generator functions are memory efficient because they yield items one at a time, rather than storing them all in memory.
