You're calling a function (getValue) that just calls a method of trend (caller), that just calls another method of trend (Ptd or Qtd or ...). You can skip all these steps, and just call the method yourself: the code that calls getValue(trend, param, per) replace with trend.<something>(per) if you're calling getValue with a static value for param, or getattr(trend, param)(per) if param is dynamic. -- Paul Hankin -- http://mail.python.org/mailman/listinfo/python-list
