enumerate yielded pairs can be unpacked in a for statement

When working with enumerate and within for loops, the yielded values can be unpacked within the for statement itself:

my_iter = ('Juan', 'Coquet')

for i, item in enumerate(my_iter):
	print(i, item)

>>>
0 Juan
1 Coquet

This makes for much cleaner code than having to use range, len and indexing into the iterable in order to get indexed pairs:

truncated...

for i in range(len(my_iter)):
	print(i, my_iter[i])

>>>
0 Juan
1 Coquet
