I think that this arises from a confusion as to what a "value" is in "pass by value". The point of it being pass by value is that there is no statement you can execute in the function that has the effect of an assignment of the expression that was passed in from the caller. This holds no matter what kind of object is passed in or what mutable properties it has or does not have. -- https://mail.python.org/mailman/listinfo/python-list
