Python splitting strings and jumbling the middle

Question

I am having trouble with a program in python...I need the program to jumble the middle of words while keeping the outer two letters intact...I believe I have successfully sp

Answer 1

I've added a regular expression to extend Burhan Khalid's solution above. This addition works for input with multiple words which I think some might find useful.

$ cat ./jumble.py
#!/usr/bin/env python
import re
import random

def jumble(s):
    l = list(s)
    random.shuffle(l)
    return(''.join(l))

line = raw_input("Input string to jumble: ")
print(re.sub(r'\b(\w)(\w+)(\w)\b', lambda m: "".join([m.group(1),jumble(m.group(2)),m.group(3)]), line))

For example:
$ ./jumble.py
Input string to jumble: I am just entering some arbitrary string
I am jsut etnrneig some aabtrrriy sritng

Note: The above example was done on a Red Hat Enterprise Linux 6.7 system with the default python-2.6.6-64.el6.x86_64
