Wow, 'cycle' is very interesting and I did not know about it before looking at your solution. A good way to solve this problem.

Cool! But how it works? I will be thankful for any explanation.

We import cycle class from itertools that returns object of type iterator. Initiate it in __init__ function and just calling next() to get the next item from this iterator in light function.

Of course, Cool. But, no need for import, % operator is enough. Such an obedient boy, I used the State design pattern -)

Cool and pythonic. There is solution like this with generator and without any imports :)

We can just define next method using match statement.

You can avoid importing cycle if you use next(self.lights, 'Green').

Nice use of the cycle method from the itertools module!
