Hi, I have this simple code: | #!/usr/bin/python | import codecs | import re | from copy import deepcopy | | class MyClass(object): | def __del__(self): | deepcopy(1) | | x=MyClass()
but I get an error: | Exception exceptions.TypeError: "'NoneType' object is not callable" in <bound method MyClass.__del__ of <__main__.MyClass object at 0x6fcf0>> ignored The problem disappears if I do anything of this: 1. change - from copy import deepcopy + import copy and call directly copy.deepcopy(1) or 2. don't store object to variable `x' or 3. don't import module `re' The first solution is OK, but I would like to know why it behaves so strange.
