Setting up Python, possible issue?

When I try to run a script in the current directory by using ./ I get an error that '.' is not recognized as an internal or external command error.

I can run them fine when running with python, just the ./ seems to be wonky. I made sure that the python.exe directory is in the path.

Any idea why using ./ isn't working? I'm trying to learn the basics of python so I can start looking at AI. My computer knowledge is average at best, I learned basic, fortran and lisp many, many years ago, but I never kept up with coding.
