Shift list elements to the right and shift list element at the end to the beginning

Question

I want to rotate elements in a list, e.g. - shift the list elements to the right so [\'a\',\'b\',\'c\',\'d\'] would become [\'d\',\'a\',\'b\',\'c\'], o

Answer 1

If you are trying to shift the elements, use collections.deque rotate method:

#! /usr/bin/python3

from collections import deque
a = deque([1, 2, 3, 4])
a.rotate()
print(a)

Result:

[2, 3, 4, 1]
