Using zip instead of indexing to handle multiple iterables

When looping through iterables of related items it is much cleaner to use zip than to use range and index into each iterable.

president = ('Obama', 'Trump')
term_beginning = (2012, 2016)

for name, year in zip(president, term_beginning):
	print(name, year)
	
>>>
Obama 2012
Trump 2016

The above code is much less visually noisy and more readable than achieving the same thing through using range and indexing.

truncated...

for i in range(len(president)):
	name = president[i]
	year = term_beginning[i]
	print(name, year)

>>>
Obama 2012
Trump 2016
