Iterators

Iterators provide a way to access elements of a collection sequentially without exposing the underlying structure

numbers = [1, 2, 3, 4, 5, 6]

iterator = iter(numbers)  # Lazy loading of the list
iterator

print(next(iterator))
print(next(iterator))

    while True:
        print(next(iterator))
except StopIteration:
    print("Reached the end of the iterator.")
