What is the difference between iterators and generators in Python?

Iterators are objects that implement the iterator protocol, allowing you to traverse through a collection. Generators, on the other hand, are a simpler way to create iterators using the yield statement.

Can you give me an example of an iterator?

Sure! Here's a simple iterator example:

class MyIterator:
    def __init__(self, limit):
        self.limit = limit
        self.current = 0

    def __iter__(self):
        return self

    def __next__(self):
        if self.current < self.limit:
            self.current += 1
            return self.current - 1
        else:
            raise StopIteration

And how about a generator?

Here's a generator example:

def my_generator(limit):
    current = 0
    while current < limit:
        yield current
        current += 1

What are the advantages of using generators over iterators?

Generators are more memory efficient since they yield items one at a time and don't store the entire collection in memory. They also make the code cleaner and easier to read.
