python error



The image above shows that there is some error. I don't understand the error here as I already have Python installed. The same error occurs when I open a file using 'python filename.py'. How do I fix this?

          you need to add Python in Environmental Variables in Windows ;)



          Follow this here or check the Python manual on the official page here



          Here also a full screen to follow:
          enter image description here



          where the path should be your python's Script folder considering the path if you change or use a custom installation. If you install through the .exe tool it usually allows you configure this on install (or during install).

            python.exe is located in the base installation directory, not the "Scripts" subdirectory -- except in a venv virtual environment. I know it's silly to require both directories in PATH. It's also silly that the directory is named "Scripts" instead of "bin". These quirks are legacies from the original port to Windows NT in the 1990s.
