What is the difference between return and yield in Python?

Can you explain the difference between return and yield in Python?

Sure! In Python, 'return' sends a value back to the caller and exits the function, while 'yield' allows a function to return a value and pause its state, resuming later.

So, does that mean yield can be used for creating generators?

Exactly! When you use 'yield', the function becomes a generator, which can produce a series of values over time instead of returning a single value.

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

Certainly! 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.

What happens if I use return instead of yield in that example?

If you use 'return' instead of 'yield', the function will return the first value and exit, so you won't get the series of numbers.
