How to run python script in visual studio and edit

edit

Hi, i am trying to run a normalization of an image thus, i used a python script to crop the image but how do i get to edit the python script and run it using a visual studio application.

Example: I took a photo of a user and we need to know the location of the eyes thus, the user is able to select his pair of eyes so we can use this to do normalization.

I am not able to do this as i used command prompt to run all the python scripts.
