[issue9703] default param values

[Georg Brandl]

Georg Brandl <georg at python.org> added the comment:

This is by design.  Parameter default values are evaluated when the function is defined, not when it is called.  Therefore, by assigning the default value to an instance attribute, you are basically sharing it between instances.
