@kaiver1212, The issue here is the way you have initialized your modules and packages. I'm happy to look at your code if that helps.

To fix the issues on PythonAnywhere:

1. EOFError:

   • Problem: input() is used, which doesn't work in a web app environment.
   • Solution: Replace input() with environment variables or HTML form input.

   data_get = os.getenv("MY_APP_DATA", "default_value")

2. ModuleNotFoundError (waitress):

   • Problem: The waitress module is missing.
   • Solution: Install waitress in your virtual environment:

   workon your_virtualenv_name  # If using a virtualenv
   pip install waitress

3. Restart the app: After fixing the issues, restart your web app in PythonAnywhere to apply the changes.
