sre_constants.error: bad character in group name
The error here is that I put a "=" where it shouldn't be. The error message is misleading. The "group name" is the stuff between the <>'s. That part's fine. What's broken is the stuff outside of the <>'s.
Unclear if it's reasonable to expect such precise error reporting here, but this one seems particularly misleading, so opening a ticket to record the observation.

The error is that '<' is not legal in a group name, and the parser is parsing the P= form. The error message could be improved by including the bad character in the message. |

See also issue14462. It will be easier to include a full group name than an invalid character. |
