at first, thanks you all for your help! So, i will follow your advice.In a moment though, i thought that "ok, do not check anything of the parameter's type but do a try/catch at the calls inside the function"
But this way, i would rather defeat the purpose because i have to try/ catch in *every* call inside the func. So, i suppose that i wouldn't want to do that and just try to make the call in whatever they passed me in. Strange world the dynamic one.... -- http://mail.python.org/mailman/listinfo/python-list
