Basic difference between iterable, iterator, iteration in python.

Question

What is the most basic definition of "iterable", "iterator" and "iteration" in Python?

I have read multiple definitions but I am unable to identify the exact meaning.

Can anyone please explain these terms in very simple way.

Answer 1

iterable means it can be gone through one item at a time or in steps.

iterator is the means of way going through them

iteration is the process.

This isn't exact but its a super basic idea. Hopefully someone can make it simpler.

~edit: Michael says it even better

Answer 2

iteration is the process of repeating something multiple times (a loop)

an iterable is an object you can loop over, because it has multiple elements (a list, a tuple, a dictionary, a string)

an iterator is an object (a pointer) that „walks“ through the iterable from element to element until a specific stop-condition occurs.
