This object is accessed through the built-in name NotImplemented. For old-style classes, special methods are always looked up in exactly the same way as any other method or attribute. This wastes space for objects having very few instance variables. However, these methods can return any value, so if the comparison operator is used in a Boolean context e. It is not very commonly used and no Python 3 support , but we have used it to implement a thread-safe blocking wrapper around an async implementation based on tornado that bounces all access to the proxied object through the ioloop, using thread-safe concurrent. We allocate about a million instances of a class like the following: This is consistent with the history of Python, from Unifying types and classes in Python 2. Where this occurs in the precedence chain depends on which descriptor methods were defined and how they were called.
