I'm happy to work on improving the text here. I'm new to contributing to
Python. I'm being mentored to work on #34431.
Once I'm done with that, I'll be better placed to contributed to this issue.

SyntaxError: assignment to keyword
1. The page constants.html incorrectly says then are in the built-in namespace.
Some of them were, once.
