That is a convenient shortcut when it works, but in my experience it tends to confuse the issue. The reason is that one of the main uses of pointers in C is implementing pass-by-reference. A C programmer told that Python variables internally hold pointers expects this code: def func(a): a = 10 ... func(x) to change the value of x. -- http://mail.python.org/mailman/listinfo/python-list
