In 2.7 the Comparisons section of stdtypes.rst only talks about __cmp__ and never mentions the rich comparison methods: "Instances of a class normally compare as non-equal unless the class defines the __cmp__() method. Refer to Basic customization) for information on the use of this method to effect object comparisons." The first sentence is false, instances can also compare as equal if they define __eq__. And since __cmp__ is gone in Python3, I think the rich comparison methods should at least be mentioned, or even emphasized over __cmp__ to help people write more forward compatible code. |

Here's my attempt at a patch. It mostly takes the text from the default branch and adds references to __cmp__. |
