if __name__ == "__main__":
    main()

this is the error- Attempted relative import in non-package

I tryed all and nothing works

Answer 1

Relative imports don't work on files that get executed as the main file.

Relative imports depend on the __name__ attribute - which is set to __main__ if you're executing that file directly.

You need to execute that file as a package

python -m import.sub_folder.x

And you need to put some __init__.py files in the folders to make python recognize them as packages
