How can I use yield with large data sets in Python?

Using 'yield' allows you to create a generator, which can handle large data sets efficiently by yielding one item at a time.

Can you show me a simple example of using yield?

Sure! Here's a basic example:

def large_data_generator():
    for i in range(1000000):
        yield i

This function will yield numbers from 0 to 999999 one at a time.

What are the benefits of using yield instead of returning a list?

The main benefits are memory efficiency and performance. Generators yield items one at a time, reducing memory usage.

Are there any limitations to using yield?

Yes, generators can only be iterated once. If you need to access the data multiple times, you'll need to store it in a list or another structure.
