2 months ago Thanks for filing a ticket. As mypy-play.net doesn't host mypy versions older than 0.980 anymore, I think it's fair to remove Python 2.7 from the default configuration.
If there's a user who really need to run an older version of mypy on mypy Playground to test Python 2.7 code, they can update this configuration to add Python 2.7 back to the list: https://github.com/ymyzk/mypy-playground/blob/55a118bd9306cfb8d1ff8617483b11134d013168/app/config.toml#L5
Current versions of mypy (>=0.980) no longer support Python2.7. This means that support on the website is effectively broken.
I don't know if it's better to just remove 2.7 entirely, or add old mypy, but the current situation is confusing as it seems to support 2.7 until you actually run it.
