Assuming that Python 3 is indeed installed, you can try to run it like so:

python3 w3c_validator.py index.html

• Error: ModuleNotFoundError: No module named 'requests' If you get this error you do not have the module requests installed in your system.

You can install requests using pip:

python3 -m pip install requests
