What are Python generators and how do they work?

Python generators are a type of iterable, like lists or tuples. They allow you to iterate through a sequence of values without storing the entire sequence in memory. This is done using the yield statement.

Can you give me an example of a simple generator?

Sure! Here's a simple generator that yields numbers from 0 to 4:

def count_up_to_five():
    for i in range(5):
        yield i

How do I use this generator in my code?

You can use the generator like this:

for number in count_up_to_five():
    print(number)

This will print numbers 0 to 4.

What are the advantages of using generators?

Generators are memory efficient because they yield items one at a time and only when required, which is great for large datasets.
