3 ways to circularly shift Python sequences

The following is a recommendation for three methods of circular shifting of Python sequences. It has a good reference value and I hope it will be helpful to everyone.

The first method: The characteristic is that it is direct and easy to understand. The disadvantage is that it is slow and can only achieve circular left shift.

def demo(lst, k):
  temp = lst[:]
  for i in range(k):
    temp.append(temp.pop(0))
  return temp

The second method: is characterized by fast speed and adaptive circular left shift (k> 0) and right shift (k7735d9a1cf2007d68ddece5f76fcbf650) and right shift (k<0).

def demo(lst, k):
  return lst[k:] + lst[:k]
