What are some examples of using yield in Python?

Can you explain what 'yield' does in Python?

Sure! 'Yield' is used in Python to create a generator, which allows you to iterate over a sequence of values without storing them all in memory at once.

Can you give me an example of how to use 'yield'?

Absolutely! Here's a simple example:

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

This function will yield numbers from 1 to n one at a time.

How do I use the generator created by that function?

You can use it like this:

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

This will print numbers 1 through 5.

What are the benefits of using 'yield' instead of returning a list?

Using 'yield' is more memory efficient because it generates items one at a time and only when requested, rather than creating a complete list in memory.
