Make a class iterable in Python
Python interview exercise on Iterators & Generators, difficulty 3 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write Cycle(items, times): looping over it goes through items, times over. Unlike the example it can be looped over again and again, because __iter__ hands out a fresh iterator each time. It also supports len().
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
