PEP-473 was recently rejected (https://mail.python.org/pipermail/python-dev/2019-March/156692.html) because it was too broad and was suggested to be broken down in smaller issues.
This issue is requesting the addition of the optional attribute
nametoNameError.The idea of having a structured attribute is to allow tools to act upon these exceptions. For example you could imagine a test runner which detect typos and suggests the right name to use.
There is a current PR (#6271) adding this functionality, but it may need to be rebased as it has been awaiting a reply since April last year.

This was added in Python 3.10 as part of gh-82711: https://docs.python.org/3/library/exceptions.html#NameError.name

I suggest you close as duplicate rather than completed.
