A couple Pythoneers are also interested in ExtremeProgramming, which endorses Pair Programming. We meet at Tully's on 45th and Meridian, in Wallingford, every Thursday night at 7:00, except the 2nd Thursday of the month, which is when the XP Seattle user's group has its big meeting. If you follow the ExtremeProgramming link, you will eventually get to details of that meeting.
