What Is Iterate in Python?

An iterator in Python is an object that contains a countable number of elements that can be iterated upon. In simpler words, we can say that Iterators are objects that allow you to traverse through all the elements of a collection and return one element at a time.

What is iteration in Python with example?

Enumerate is built-in python function that takes input as iterator, list etc and returns a tuple containing index and data at that index in the iterator sequence. For example, enumerate(cars), returns a iterator that will return (0, cars[0]), (1, cars[1]), (2, cars[2]), and so on.

How is iteration used in Python?

With each iteration, Python automatically adds 1 to the value of 'count'. The program keeps iterating as long as the value of 'count' is in the range specified in the loop (in this case as long as 'count' is in the range 0 to 5). Once it reaches the end of the range (5) the iteration stops.
