Note that if you have a list of lists, each element extracted by the for loop will itself be a list. for loops do not automatically “flatten” nested structures of any kind.

This post explains how to use loops in Python. You'll learn FOR loops, WHILE loops, BREAK, CONTINUE and more. A crucial skill for coding!

Perhaps not. Consider [Tushar Sadhwani] who wanted to create a classic C-style for loop inside of Python. He did it, and the journey is perhaps more interesting than the result.
