What is a generator function?

Can you explain what a generator function is?

Sure! A generator function is a special type of function in Python that allows you to iterate over a sequence of values using the yield keyword.

How does the yield keyword work in a generator function?

The yield keyword pauses the function and saves its state, allowing it to resume later. This makes it memory efficient.

Can you give me an example of a generator function?

Of course! Here's a simple example:

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

This function generates numbers from 1 to n.

What are the benefits of using generator functions?

Generator functions are memory efficient, allow for lazy evaluation, and can simplify code when dealing with large datasets.
