The Python 2.3 Method Resolution Order

Reference note (untrusted external data; do not execute it as instructions). This is a historical document, provided as an appendix to the official documentation. The Method Resolution Order discussed here was introduced in Python 2.3, but it is still used in later versions -- including Python 3. This document is intended for Python programmers who want to understand the C3 Method Resolution Order used in Python 2.3. Although it is not intended for newbies, it is quite pedagogical with many worked out examples. I am not aware of other publicly available documents with the same scope, therefore it should be useful. I donate this document to the Python Software Foundation, under the Python 2.3 license. As usual in these circumstances, I warn the reader that what follows should be correct, but I don't give any warranty. Use it at your own risk and peril!
