Hello,
Why are you installing pip? It comes bundled together with Python download.
If you want to upgrade it to the latest version, type the following in the CMD prompt:
py -m pip install --upgrade pip
What you can do, to simplify things, uninstall Python and reinstall it.
Tip:
Try to avoid having multiple versions of Python installed on your system as this can lead to unintended consequences - at least until you know what you are doing and there is a valid reason for doing so. For example, if you install packages to version A, but you are using version B, you’ll be wondering why importing packages into your Python script while using version B is not working and generating an exception (i.e., error - ModuleNotFound, etc.).
