I'm trying to install kivy, but my computer doesn't recognise me as having installed pip so I run get-pip.py through my cmd and this is what happens:
When I type: cd \Users\jmcco\Desktop\python-3.6.2-embed-amd64\ and then type: python get-pip.py I get an error message that reads: TypeError: expected str, bytes or os.PathLike object, not NoneType

The whole cmd output reads:

    main()

    bootstrap(tmpdir=tmpdir)

So, if Windows doesn't recognize something as a script (for example, if you're using .py extension), then it will try to open the file in whatever it has as a default editor. In your case, it's Atom. In my case (when I used Windows) it was Notepad++.
Regardless, you need to use the command prompt to get this working:

Press Windows-r A prompt will show up.
Type cmd in the prompt.
Press enter This will drop you into the command prompt.
Type python then hit enter If you have an error, then you don't have Python.
Paste/type cd \Users\jmcco\Desktop\python-3.6.2-embed-amd64\
Type python get-pip.py

Alternatively, you could use Anaconda, which should allow you to use a GUI to install.
