How to loop through a class instance?

Question

I was asked this question. Given the code:

class MockList:
    ...code_here...

for i in MockList():
    print(i)

Expected result of for loop:

1 2 3 4 5

How can I do this?

If you implement an __iter__() method, you can do this functionality:

class MockList:

    def __iter__(self):
        return iter(range(1, 6))

for i in MockList():
    print(i)
