Thanks a lot in advance
Implementing __dir__ as an instance method works: >>> class Foo(object): ... def __dir__(self): return ["python"] ... >>> dir(Foo()) ['python'] So if you want to customise dir(Foo) you have to modify the metaclass: >>> class Foo: ... class __metaclass__(type): ... def __dir__(self): return ["python"] ... >>> dir(Foo) ['python'] -- http://mail.python.org/mailman/listinfo/python-list
