https://docs.python.org/3.15/whatsnew/3.15.html:
pprint now uses modern defaults: indent=4, width=88, and the default compact=False output is now formatted similar to pretty-printed json.dumps(). (Contributed by Stefan Todoran, Semyon Moroz and Hugo van Kemenade in gh-112632 and gh-149189.)

For all our attempts to build python-dirty-equals with Python 3.15, see:

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.15:
https://copr.fedorainfracloud.org/coprs/g/python/python3.15-b1/

Let us know here if you have any questions.

Python 3.15 is planned to be included in Fedora 45.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.15.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
