Have you considered/planned to rework a bit the beginning of the page too?
(Technically the issue is about the Sequence types section, but the whole page could be improved.)
IMHO the sections about Truth value testing, Boolean operations, and Comparison are out of place there, and True/False/None should be described instead.
The idea is that a developer new to Python should be able to come to this page, take a look at the headers and figure out what the main types are (what you did so far is already a good step in the right direction).
