[Message part 1 (text/plain, inline)]

Using emacs 28.2 on Arch Linux.
Syntax highlighting using the default python-mode (python.el) is 
inconsistent.
Multiple users in the #emacs channel who all tested this with the -Q 
option all report the same results.

Please see attached image for the first example.

Notice how the variable 'money' for example is randomly highlighted.

Full code here: Paste.rs <https://paste.rs/K2r.py>

For the above code, when opened in emacs -Q if you go to the last 
instance of 'money' where it says 'money += bet * 2' and press RETURN 
after the end of that line, suddenly it gets highlighted, and then if 
you go to the previous instance of that and do the same, the 
highlighting of the one below disappears.

The same was confirmed by multiple users from the #emacs channel.

Please advise.

Best regards,
Stan

Hi,

I think this could be fixed already on master (possibly by the patch in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=51362).  I've attached an
image of what your snippet looks like on Emacs built ~1 hour ago.

Thanks, Laurence

Does the above image match your expectations of how this should be
fontified?  If so, I think this bug should be closed.

Hello,
Sorry for the late reply.
Yes that seems fine.
Alternatively you can leave variables completely unstyled.

Cheers,
Stan
