I'm not sure what certificates you mean? Could you tell us exactly which
vesion of Python you downloaded? Was it the official python.org distro
opr perhaps one of the scientific ones like Annaconda or Enthought?

Again, I'm not sure what you mean by the start window.
But I'm not a Mac user so it may be Mac specific.

Python is an interpreter and usually used from a command
line - the terminal app in MacOS I believe? Or from inside
an IDE such as Eclipse, netbeans or Visual Code.

Basic Python comes with a basic IDE called IDLE, but
I'm not sure how you find/launch that on a Mac.

Does this "Python Window" containa prompt that looks like >>>
If so it may be IDLE.(or some other IDE)
Can you give a link to the tutorial so we can see what you see?
