What is the yield statement in Python?

Can you explain what the yield statement does in Python?

Sure! The yield statement is used in Python to create a generator. It allows you to iterate over a sequence of values without storing them all in memory at once.

How does using yield differ from returning a value?

When you use return, the function exits and sends a value back. With yield, the function can pause and resume, allowing it to produce a series of values over time.

Can you give me an example of a function using 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.

What are the benefits of using generators with yield?

Generators are memory efficient since they yield one item at a time. They also allow for lazy evaluation, meaning values are produced only when needed.
