Causes modification of an list object to change the values of the object already inside the list.
Example code :
import random
a =[]
b = [1 , 2 , 3 , 4]
for i in range (15):
random.shuffle(b)
a.append(b)
for j in a:
print j
Expected Behaviour : the list referenced by b , should be appended to a , creating a list of random permutations of b.

Sorry, this is the expected behavior. Copy the list if you want a different one. |
