to randome a list, we use the shuffle method, which is a part of random python library

import random
number_list = [7, 14, 21, 28, 35, 42, 49, 56, 63, 70]
print ("Original list : ",  number_list)
random.shuffle(number_list) #shuffle method
print ("List after first shuffle  : ",  number_list)
random.shuffle(number_list)
print ("List after second shuffle : ",  number_list)

OUTPUT

Original list : [7, 14, 21, 28, 35, 42, 49, 56, 63, 70]

List after first shuffle : [7, 14, 56, 21, 35, 70, 49, 42, 28, 63]

List after second shuffle : [35, 63, 70, 21, 42, 28, 49, 56, 14, 7]
