[issue32573] All sys attributes (.argv, ...) should exist in embedded environments

STINNER Victor added the comment: The issue has been fixed in Python 3.8. See PEP 587 and http://docs.python.org/dev/c-api/init_config.html for the larger scope. For Python 3.7, the fix is trivial: don't add the following 2 lines in your application: if not hasattr(sys, 'argv'): sys.arg

[issue32573] All sys attributes (.argv, ...) should exist in embedded environments
