Hi, I am kinda new to python and is trying to write a little program to work out sports fixtures but i am a bit stuck. I want to take say 4 players and work out a fixture like this:

round1
player1 vs player3
player2 vs player4

round2
player1 vs player2
player3 vs player4

round3
player1 vs player4
player2 vs player3

So i know how to work out the amount of rounds and amount of matches like this:

teams = open('teamlist.txt', 'r')
teams = teams.read()
teams = teams.strip()
ghostPlayer = False
teamCounter = 0

for line in teams.split("\n"):
  teamCounter += 1

if teamCounter % 2 == 1:
   ghostPlayer = True
   teamCounter += 1
   print "odd"
 else:
   print "even"
 
if ghostPlayer == False:
     print "GhostPlayer = %s, there is %s players" % (ghostPlayer, teamCounter)
else:
     print "There is one GostPlayer(%s) and %s real players" % (gostPlayer, (teamCounter - 1))     
 rounds = teamCounter - 1
 matches = teamCounter / 2

My problem really is that i don't know how to do the actual fixture bit, it would be very much appreciated if someone can help me

The itertools module includes the combinations function to assist in building the set of linear combinations for a list:

>>> import itertools
>>> for matchup in itertools.combinations(['team1','team2','team3','team4'], 2):
...     print matchup
... 
('team1', 'team2')
('team1', 'team3')
('team1', 'team4')
('team2', 'team3')
('team2', 'team4')
('team3', 'team4')

From there, you only have to worry about properly putting them into sets.
