Hello. I've done the following in CPython 2.7.3 and 3.3.0 (and also in PyPy 2.0b1):
>>> import weakref >>> x = set() >>> y = weakref.proxy(x) >>> x.__class__, type(x), isinstance(x, set) (<class 'set'>, <class 'set'>, True) >>> y.__class__, type(y), isinstance(y, set) (<class 'set'>, <class 'weakproxy'>, True) So, type doesn't use object's __class__ to determine its class. I'm looking for some CPyhton implementation details - how does class identification with type() work? According to CPython's sources it looks like there is a "marker" of actual object's class associated with each PyObject - _typeobject struct, which is used to identify the class by type(). Am I right? Thank you. - Ivan Yurchenko. -- http://mail.python.org/mailman/listinfo/python-list
