pip is designed to upgrade python packages and not to upgrade python itself. pip shouldn’t try to upgrade python when you ask it to do so.
Don’t type pip install python but use an installer instead.
Basically, pip comes with python itself.Therefore it carries no meaning for using pip itself to install or upgrade python.
Thus,try to install python through installer itself,visit the site “https://www.python.org/downloads/” for more help.
Thank you.
