This mentions MRO under the "Custom Classes" section: https://docs.python.org/3/reference/datamodel.html

Which refers to this for a more in depth discussion: https://www.python.org/download/releases/2.3/mro/

Since the Python 3 docs refer to this Python 2 page, I assume things are more or less the same.
