def create_logger(app):

Get the Flask app's logger and configure it if needed.

The logger name will be the same as app.import_name.

When ~flask.Flask.debug is enabled, set the logger level to logging.DEBUG if it is not set.

If there is no handler for the logger's effective level, add a ~logging.StreamHandler for ~flask.logging.wsgi_errors_stream with a basic format.

@LocalProxy
def wsgi_errors_stream():

Find the most appropriate error stream for the application. If a request is active, log to wsgi.errors, otherwise use sys.stderr.

If you configure your own logging.StreamHandler, you may want to use this for the stream. If you are using file or dict configuration and can't import this directly, you can refer to it as ext://flask.logging.wsgi_errors_stream.

Returns
`t.TextIO`	Undocumented
