...Object_Str() API called PyObject_Unicode(). It behaves in the same way as the former, but assures that the returned value is an Unicode object (applying the usual coercion if necessary). The comparison operators support "rich comparison overloading" (PEP 207). C extension types can provide a rich comparison function in the new tp_richcompare slot in the type object. The cmp() function and the C function PyObject_Compare() first try the new rich comparison operators before trying the...
...Object_GC_New or PyObject_GC_NewVar to allocate objects and PyObject_GC_Del to deallocate them rename PyObject_GC_Init to PyObject_GC_Track and PyObject_GC_Fini to PyObject_GC_UnTrack remove PyGC_HEAD_SIZE from object size calculations remove calls to PyObject_AS_GC and PyObject_FROM_GC Two new functions: PyString_FromFormat() and PyString_FromFormatV(). These can be used safely to construct string objects from a sprintf-style format string (similar to the format string supported by PyErr_For...

...objects, instead of strings. Objects which have Python equivalents are converted to Python objects, other objects are wrapped. This can be configured through the wantobjects method, or Tkinter.wantobjects. The PyBSDDB wrapper around the Sleepycat Berkeley DB library has been added as the package bsddb. The traditional bsddb module is still available in source code, but not built automatically anymore, and is now named bsddb185. This supports Berkeley DB versions from 3.0 to 4.1. For help con...
...Object Adaptation - Evans I never even understood what this PEP was about until Alex Martelli explained it to me. I think it's similar to an operation in Zope 3 that looks for an adapter to a given object that implements a given interface. If the object itself implements the interface, it is returned itself; otherwise a table of registered adapters is searched systematically to find the most suitable adapter. But that's about all I know of the subject, and I think it should remain ...

You then find that although there are plenty of feet objects implemented in the past in many other languages, you cannot get access to one. But seeing as Java is so cool, you dont care and go around shooting anything else you can find. —Mark Ham...
