KeyError in get_default_logging_config

If sys.executable is set to pythonw.exe calling get_default_logging_config results in a KeyError because it tries to delete a key that doesn't exist.

Received the same error. Issue is that the 'del' needs to be two lines, not one:
Original:
del config["handlers"]["loggers"]
Corrected:
del config["handlers"]
del config["loggers"]
