Python: Traverse List Backwards

If you want to traverse a list in Python backward, i.e. from the reverse direction (right-to-left) then you can make use of the built-in function reversed()

Example 1: With Numbers

numbers_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

for num in reversed(numbers_list):
    print(num, end=" ")

Example 2: With Strings

alphabets_list = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j']

for alphabet in reversed(alphabets_list):
    print(alphabet, end=" ")

Reference:

"Return a reverse iterator. seq must be an object which has a __reversed__() method or supports the sequence protocol (the __len__() method and the __getitem__() method with integer arguments starting at 0)."
