Python 3.1: >>> def apply_spreaded(funcs, values): ... num_funcs = len(funcs) ... num_values = len(values) ... for i, func in enumerate(funcs): ... func(values[(i * num_values) // num_funcs]) >>> apply_spreaded([print] * 8, range(5)) 0 0 1 1 2 3 3 4 -- http://mail.python.org/mailman/listinfo/python-list
