# Scramble word re-arrange characters of word by using simple string manipulation and Random.
import random
s= raw_input("Give Word:")
n=0
st=[]
while n<>len(s):
    st.append(s[n])
    n=n+1
print st
n=0
rst=[]
while n<>len(s):
    rno=random.randint(0,len(s)-1)
    if rst.count(rno)==0:
        rst.append(rno)
        n=n+1
print rst
n=0
ost=''
while n<>len(s):
    ost=ost+ st[rst[n]]
    n=n+1
print ost

Basic string maniplution and use of random. Basic algorithm useful in advance programming.Kids can play as a game.

Another way. This could also be done with:

import random
word = raw_input('Word: ')
print ''.join(random.sample(word, len(word)))

Heres another way. Heres something I whipped up just then

def randomize(string):

string = list(string)
 temp = string[:]


for i in range(len(string)):

    randomnum = int(random.random()*len(temp))

    string[i] = temp[randomnum]

    temp.remove(string[i])


return ''.join(string)

Basically, what it does is just take in a string, convert it to a list, and make a temporary copy.

Once it has done this, it then iterates in a loop equal to the length of the original string, and in each loop, takes a random value from the temporary array, and replaces the next position in the original string with this value.

At the end, the value is removed from the temporary array.
