start for loop from the end python code example

Example 1: python for loop backwards

for i in range(len(item)-1, -1, -1):
        print(item[i])

Example 2: python iterate backwards through list

>>> a = ["foo", "bar", "baz"]
>>> for i in reversed(a):
...     print(i)
... 

or

>>> for i, e in reversed(list(enumerate(a))):
...     print(i, e)
