from itertools import cycle # using itertools cycle, an example. # this allows the cyclic production of values 1-5 thecycle = cycle([1,2,3,4,5]) # you can do the same thing yourself # without itertools if you want to. def mycycle(): num = 0 while 1: yield (num % 5)+1 num +=1 doityourself = mycycle() for i in range(20): # value output comparison print(next(thecycle),next(doityourself)) # the advantage of itertools is mutiple features # are built in and ready to go. Read about # generators as a starting point to learn more
