This is less like theforkeyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. With theforloop we can execute a set of statements, once for each item in a list, tuple, set etc. ...
This provides us with the index of each item in ourcolorslist, which is the same way that C-styleforloops work. To get the actual color, we usecolors[i]. for-in: the usual way Both the while loop and range-of-len methods rely on looping over indexes. But we don’t actually care...
