Basic Output Using output functions, you until the user submits the form. The output function is used to output content to the browser in real time. The input and output behavior of PyWebIO is consistent with the console program. That’s why we say datetime @use_scope('time', clear=True) def show_time(): put_text(datetime.now()) When calling show_time() for the first time, a time scope will be created, and the current time will be output to it.
