Side note: It’s generally best to copy and paste full error messages. There may be important details in the error message that you don’t notice, and copy&paste makes it harder to make mistakes.

You’re missing a -. It’s pip3 install --upgrade pip with --, not -.

If that doesn’t work, you may need to use pip3 install --user --upgrade pip (and pip3 install --user name_of_package whenever you install a new package). The --user flag makes pip install packages just for you (in your home directory) instead of for the whole system.

Hope this helps, and have fun learning Python!
