Can you explain the concept of generators in Python and provide an example of how they can be used?

Certainly. Generators in Python are a simple way to create iterators using functions. They allow you to iterate through a potentially large set of data efficiently by generating values on-the-fly, rather than storing everything in memory. Here's an example of a generator function that yields squares of numbers:

def generate_squares(n):
    for i in range(n):
        yield i * i

# Usage
squares_generator = generate_squares(5)
for square in squares_generator:
    print(square)
