how to write method/function named movel( s, k) that moves all the elements of the 's' arr-CodePudding

this is my code below and please help me find out the the expected output[ 4,5,6,0,0,0]

def movel(s, k):
  n=len(s)
  j=0
  n_arr=s[:k]
  return (s[k::] n_arr[::])
  for j in range(0, n):
    print(s[j], end=' ')


s=[1,2,3,4,5,6]
k=3 
movel(s,k)

*Output : [4,5,6,1,2,3] *

CodePudding user response：

You could do use index slicing

def movel(s, k):
    if k > len(s):
        return [0] * len(s) # you decide how to handle this case
    return s[k:]   [0] * (len(s) - k)

Think of it this way, we change the head of the list and fill the rest with zeros.
