def shift_left(my_list):
    my_list = my_list[::-1]
    print(my_list)

shift_left(['1', '2', '3', 'monkey'])

my_list = shift_left(['1','2','3','monkey'])
print(my_list)
my_list + ["donkey"]

Error message:

TypeError: unsupported operand type(s) for +: 'NoneType' and 'list'

It happened because you `print`, not `return` in your function – crayxt Jun 25 '21 at 16:53
Instead of `print(my_list)`, use `return my_list` – rpb Jun 25 '21 at 16:55
