ModuleNotFoundError: No module named 'res'

This error is typically seen in Python when you try to import a module that does not exist or is not installed in your Python environment. In this case, the error is indicating that there is no module named 'res' that can be found.

To resolve this error, you should check that:

- The module name is spelled correctly.
- The module is installed in your Python environment.
- The module is in a location that can be found by Python (e.g., in a directory listed in the PYTHONPATH environment variable).

If you are trying to use a third-party module, you may need to install it using pip or another package manager. If you are trying to use a module that you have created yourself, make sure that it is saved in a directory that Python can find and that it has the correct name and structure.
