Two random lists from one list

[noydb]

Hello All,

I am just looking to see if there is perhaps a more efficient way of
doing this below (works -- creates two random teams from a list of
players). Just want to see what the experts come up with for means of
learning how to do things better.

Thanks for any responses!

###
import random
players = ["jake", "mike", "matt", "rich", "steve", "tom", "joe",
"jay"]
teamA = random.sample(players, 4)
print teamA
teamB = []
for p in players:
if p not in teamA:
teamB.append(p)
print teamB

import random
players =
teamA = random.sample(players, 4)
print teamA
teamB = []
for p in players:
    if p not in teamA:
        teamB.append(p)
print teamB

How about:

players = ["jake", "mike", "matt", "rich", "steve", "tom", "joe",
"jay"]
random.shuffle(players)
teamA, TeamB = players[:4],players[4:]

teamA, teamB

(['tom', 'mike', 'jay', 'rich'], ['jake', 'matt', 'joe', 'steve'])

I'd be tempted to do

temp = players[:] # copy players
random.shuffle(temp) # you could directly shuffle players
# if you don't care about mangling it
team_a = temp[:4]
team_b = temp[4:]
del temp # optional

This assumes you want balanced-ish teams.
