You have said the value that is copied is a pointer to the object.
This assumes that "call by value" means "call by copying the value". That assumption is WRONG. It doesn't mean that. It means "call by ASSIGNING the value." So, you can think of the value of an expression as being an object, as opposed to a reference to an object, if you want. But then you need to consider what it means to assign that value to a name. Obviously it doesn't mean copying the value -- it must mean making the name refer to the value somehow. The same thing happens when the value is passed to a function. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
