PARSING ARGS is Added on File Save

After updating to the latest version, when I save the file I worked on it automatically adds this line to the top of my file.

PARSING ARGS - ['-', '--filename', '/Users/myname/projects/project-1/hello.py']

The name of the file changes depending on the name of the file I change. I cant do any work at the moment because of it.

Please help.
Thanks
