Is there any way to restart the web server from within the bash console given in the browser for PythonAnywhere? I have searched google for a while and have not found anything relevant.
There is a file for each of your web apps in /var/www. The naming of the file should make it obvious which file applies to which web app.
Type
touch /var/www/<filename>
(where <filename> is the name of the file that is for the web app you want to restart) and server will notice that the modified date of the file has changed and restart your app.
