What are iterators and generators in Python?

What are iterators and generators in Python?

Iterators are objects that allow you to traverse through a collection, while generators are a type of iterator that yield values one at a time.

Can you give me an example of an iterator?

Sure! A simple iterator can be created using a class that implements the __iter__() and __next__() methods.

And what about a generator?

A generator can be created using a function with the yield keyword. For example, a function that yields numbers from 1 to 5.

How do I use a generator in a loop?

You can use a generator in a loop just like a list. For example, you can use a for loop to iterate through the values it yields.
