• Unifying types and classes in Python 2.2

  ...getattribute__, bear in mind that it is easy to cause infinite recursion: whenever __getattribute__ references an attribute of self (even self.__dict__!), it is called recursively. (This is similar to __setattr__, which gets called for all attribute assignments; __getattr__ can also suffer from this when it is carelessly written and references a non-existent attribute of self.) The correct way to get any attribute from self inside __getattribute__ is to call the base class's __getattrib...

• Python 2.0

  ...GetAttr() and PyObject_SetAttr() now accept Unicode objects for the attribute name. See note on getattr() above. A few bug fixes to argument processing for Unicode. PyArg_ParseTupleAndKeywords() now accepts "es#" and "es". PyArg_Parse() special cases "s#" for Unicode objects; it returns a pointer to the default encoded string data instead of to the raw UTF-16. Py_BuildValue accepts B format (for bgen-generated code). Internals On Unix, fix code for finding ...

• Notes

  ...getattr() operation with AttributeError exceptions changed into ImportError. "from M import *" now looks for M.__all__ to decide which names to import; if M.__all__ doesn't exist, it uses M.__dict__.keys() but filters out names starting with '_' as before. Whether or not __all__ exists, there's no restriction on the type of M. File objects have a new method, xreadlines(). This is the fastest way to iterate over all lines in a file: for line in file.xreadlines(): ...do something to...

• Python 2.4.1 - Release Notes

  ...getattr__ is now called __getattribute__. This method, if defined, is called for every attribute access. A new __getattr__ hook more similar to the one in classic classes is defined which is called only if regular attribute access raises AttributeError; to catch all attribute access, you can use __getattribute__ (for new-style classes). If both are defined, __getattribute__ is called first, and if it raises AttributeError, __getattr__ is called. The __class__ attribute of new-style objects ca...

• Notes

  ...getattr hooks. If an old-style instance didn't have a __del__ method, but did have a __getattr__ hook, and the instance became reachable only from an unreachable cycle, and the hook resurrected or deleted unreachable objects when asked to resolve "__del__", anything up to a segfault could happen. That's been repaired. dict.pop now takes an optional argument specifying a default value to return if the key is not in the dict. If a default is not given and the key is not found, a KeyEr...
