Hi everyone, first I'm not quite sure if this is the right place to make this kind of suggestion/ask question but, `itertools.cycle` makes a copy of the iterable its given and as the note says: this may require significant auxiliary storage. Maybe I don't see the reason why this is nescessary but, shouldn't this work just as well: ``` def cycle(iterable): # cycle('ABCD') --> A B C D A B C D A B C D ... while iterable: for element in iterable: yield element ``` Instead of the current:
``` def cycle(iterable): # cycle('ABCD') --> A B C D A B C D A B C D ... saved = [] for element in iterable: yield element saved.append(element) while saved: for element in saved: yield element ```
