[issue27607] Enums never match if imported from another file

Ethan Furman added the comment: Oh, forgot to mention I also tried testing as just 'main.py' from inside the test directory (that's what accounted for one of the two error messages). -- ___ Python tracker

[issue27607] Enums never match if imported from another file

Ethan Furman added the comment: Sylvia, if you have any control over the name of your zip files, please use something shorter. ;) The files inside are a 'main.py' and a 'module.py' -- notice there is no '__main__.py'. So it can't be executed as 'python3 -m blahblah'. I tried renaming
