How do you sort a name list and list in random order?

[Frank & Janny Plaza]

I am trying to write a program in which the users will each enter their names and when all names have been entered, I want to randomly sort this list of names several times and then show the order in which they have beeen sorted. I tried using sort(), but this only sorts the names in the order in which they are entered. Any suggestions?
Thanks, Cisco

I'm not quite sure what "sorts the names in the order in which
they are entered" means, but take a look at the shuffle function
in the random module:

http://www.python.org/doc/current/lib/module-random.html

import random
x = range( 10 )
x [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
random.shuffle( x )
x [5, 8, 3, 0, 1, 7, 6, 9, 2, 4]
random.shuffle( x )
x [5, 2, 4, 1, 3, 9, 6, 0, 7, 8]
random.shuffle( x )
x

[2, 8, 7, 5, 0, 4, 3, 9, 6, 1]

HTH,

Hi Frank, Janny or Cisco!

My first idea was the following:

==============
import random

def shuffle(l):
randomly_tagged_list = [(random.random(), x) for x in l]
randomly_tagged_list.sort()
return [x for (r, x) in randomly_tagged_list]


t=["Anna", "Berta", "Caesar", "Doris"]

print shuffle(t)
print shuffle(t)
print t
==============

You may want to also have a look at random.shuffle, however.

Greetings,

Hi!

sort

"randomly sort"??????? I mean, for me "randomly" means somewhat of the
opposite of "sorted"...

What about shuffle()?
