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

The question seems to imply to me that the list itself should be modified rather than a new list created. A simple in place algorithm is therefore:

lst = [1, 2, 3, 4, 5]

e1 = lst[-1]
for i, e2 in enumerate(lst):
    lst[i], e1 = e1, e2

print(lst)

Giving:

[5, 1, 2, 3, 4]
