>>> import random >>> s="abcdef123" >>> ''.join(random.sample(s,len(s))) '1f2bde3ac' 

There is a function shuffle in the random module. Note that it shuffles in-place so you first have to convert your string to a list of characters, shuffle it, then join the result again.

import random l = list(s) random.shuffle(l) result = ''.join(l) 

Python Provides the various solutions to shuffle the string:

1. External library: python-string-utils

• first install the python-string-utils library
  • pip install python_string_utils
• use string_utils.shuffle() function to shuffle string
• please use the below snippet for it

Code Snippet

import string_utils print string_utils.shuffle("random_string") 

Output:

drorntmi_asng 

2. Builtins Method: random.shuffle

Please find the code below to shuffle the string. The code will take the string and convert that string to list. Then shuffle the string contents and will print the string.

import random str_var = list("shuffle_this_string") random.shuffle(str_var) print ''.join(str_var) 

Output:

t_suesnhgslfhitrfi_ 

3. External Library: Numpy

import numpy str_var = list("shuffle_this_string") numpy.random.shuffle(str_var) print ''.join(str_var) 

Output:

nfehirgsu_slftt_his 

you can use more_itertools.random_permutation

from more_itertools import random_permutation s = 'ABCDEFGHIJ' ''.join(random_permutation(s)) 

output:

'DFJIEABGCH'
