Here is code based on Lee's sample:

### adding an instance method after the fact
import new

class c:
  def __init__(self):
    self.a1 = 1
  def m1(self):
    self.a2 = 2

def m2(self): #note, outside of class c definition
  self.a3 = 3

c1 = c()
c1.m2 = new.instancemethod(m2, c1, c)

c1.m2()
print c1.a3
