sort_keys is only equivalent to order preservation if the key order you want *is* alphabetical order. While that's typically a good enough assumption for JSON, it's not the case for things like CSV column order, TOML or ini-file setting order, etc. Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
