Consider the following trivial problem: Lets say we want to print string "Today is Sunday" 100 times to the console. Its a strange construct even to seasoned Python coders. When used in conjunction with for- loops it basically means "find some item in the iterable, else if none was Im wondering how Python coders read this construct in their head (or aloud, if you like).
