Solution Exercise 32: Python algorithm which move the elements of a list

Exercise 32

Write a Python program that move the first 3 elements of a given list and place them at the end of the list. Example if L = [25, 13, 11, 1, 4, 31, 18, 6, 12, 1, 7], the program returns: the list: [1, 4, 31, 18, 6, 12, 1, 7, 25, 13, 11]

Solution

def moveListElements (L):
     # remove the three elements from the list
     L1 = L [3 ::]
     # extraction of the first three elements
     L2 = L [0: 3]
    
     return L1 + L2
    
L = [25, 13, 11, 1, 4, 31, 18, 6, 12, 1, 7]
print (moveListElements(L))
# The output is: [1, 4, 31, 18, 6, 12, 1, 7, 25, 13, 11]
