Let me guess... What you want to is in fact to call a method by it's
name ? If so, getattr(obj, name) is your friend:

class Knight(object):
  def __init__(self):
    self._saywhat = "ni"
    self._wantwhat ="shrubbery"

  def says(self):
    return self._saywhat

  def wants(self):
    return self._wantwhat

k = Knight()

print getattr(k, "says")()
print getattr(k, "wants")()
