Map with an extra parameter

[ml1n]

Hi,
I'm not really sure how to explain this so maybe some example code is
best.  This code makes a list of objects by taking a list of ints and
combining them with a constant:

class foo:
  def __init__(self):
     self.a = 0
     self.b = 0

def func(a,b):
  f = new foo()
  f.a = a
  f.b = b
  return f

constants = [1]*6
vars = [1,2,3,4,5,6]
objects = map(func,vars,constants)

In the real world I need to do this as quick as possible (without
resorting to c) and there are several constants. (The constant is only
constant to each list so I can't make it a default argument to func.)
My question is, can anyone think of a way to do this efficiently
without having to use the `dummy` list of constants and would it be
quicker?
