Trouble installing python

[Steven via Python-list]

Good afternoon,

I originally started with the latest version of python (3.7), but I was unable 
to figure out how to get to script mode.  There weren't any tabs at the top of 
the interactive mode window.

So I decided to uninstall 3.7, and try 3.5.2 (since that is the version my 
online instructor is using)  now i keep getting a screen asking me to modify, 
repair, or uninstall (screen shoot attached).  I have clicked repair twice now, 
and modify once and I still get the same message.

Am I doing something wrong in 3.7 that is maybe hiding script mode?

Thank you

Steven

Modify setup

Good morning,

I have uninstalled and reinstalled different versions of Python, and continue 
to get the "modify setup" box when I try to open.

Is there something I'm doing wrong?
