Hi,
let's simply start with an example:
#!/usr/bin/python2.6
import numpy as n
def calculate(a,b=3,c=4):
print b
return n.sqrt(n.exp(a*b+c)/n.exp(c)**2)

p = Pool(processes=2)
a_list=range(10)

Maybe there's a prettier way to do this, but I did it explicitly like
this because the "transpose" I needed was specific to the structure of
the game payoff matrix; it isn't a normal mathematical transpose. I

You need a loop, and putting a while True: around the whole thing
solves it nicely. Don't *call* the function again, just loop back
and do the operation again. That's what loops are for.

I'm trying to figure out how to define a class so that its instances
have a method that return a different object of the same class.
In particular, I'm trying to run a simple prisoner's dilemma game, and
