What are some use cases for generators in Python?

Generators in Python are useful for handling large datasets, creating infinite sequences, and managing memory efficiently.

Can you give me an example of a generator in action?

Sure! Here's a simple generator that yields squares of numbers:

def square_generator(n):
    for i in range(n):
        yield i ** 2

You can use it like this:

for square in square_generator(5):
    print(square)

How do generators compare to regular functions?

Generators return an iterator and maintain state, allowing them to produce values on the fly, while regular functions return a single value and lose their state.

What are the benefits of using generators?

Generators are memory efficient, allow for lazy evaluation, and can simplify code for iterating over large datasets.
