New submission from Michael Kesper:

Please look at http://stackoverflow.com/questions/41932287/how-can-i-create-a-loop-for-these-if-statements/41932494?noredirect=1#41932494 

For beginners, it would be good to introduce the concepts of 'pythonic' dealing with sequences (iterators) and streams (generators) as soon as possible and everywhere where sequenceable data structures are discussed.

It is a common idiom in other languages to access members of sequences with counters, risking off-by-one errors or IndexErrors.

If beginners aren't introduced to the 'right' concepts soon enough, they might have a hard time figuring out the 'iterator' way.
Iterators should at least be mentioned in https://docs.python.org/3/tutorial/datastructures.html#looping-techniques.
