gabriele, This works (A, Test, and o as defined by you):
>>> a=A() >>> o.do(a, 10) 10 Your problem is that do() really has two parameters, an A instance and whatever you want to print. Why not do this: >>> def newdo(m): ... print m ... >>> newdo(10) 10 >>> o=Test() >>> o.newdo = newdo >>> o.newdo(10) 10 Robert -- http://mail.python.org/mailman/listinfo/python-list
