问题 I have 2 forms on an HTML page with the same action URL (e. g. action = "/example"). In my Python Flask .py file, I have 2 routes with the same url, but I want 1 route to have the PUT method and the other to have the DELETE method (e. g. @app.route('/example'), methods=['PUT'] vs. @app.route('/example'), methods=['DELETE']).
