this is my code :
import random
a = [12,2,3,4,5,33,14,124,55,233,565]
b=[]
for i in a:
b.append(random.choice(a))
print a,b
but i think maybe has a method like sort named randomList
has this method in python .
thanks

import random
a = [12,2,3,4,5,33,14,124,55,233,565]
b = a[:]
random.shuffle(b)
# b: [55, 12, 33, 5, 565, 3, 233, 2, 124, 4, 14]
This will not modify a.
To modify a inplace, just do random.shuffle(a).

I think you are looking for random.shuffle.

you could use random.shuffle
random.shuffle(a)
would give a random order of a.

>>> random.sample(a, len(a))
[14, 124, 565, 233, 55, 12, 5, 33, 4, 3, 2]
this has several advantages over random.shuffle:
- a new list is returned (no changes to original a)
- the resulting list is in selection order so that all sub-slices will also be valid random samples
- in random.shuffle, most permutations of a long sequence can never be generated.
All elements of a are part of the returned list. See more here.
