I want to make a program taking a cropped screenshot (like Windows+Shift+s) and save it as variable, not as a file.

How do I Programmatically open this win+shift+s window?

How to directly get the output without saving this as a picture?


I'm using python
you will need to:

trigger the Print screen key (any keyboard library should allow it)
retrieve the data from the clipboard (you will maybe forced to save it as a temporary file and then read from it)
then parse the data it will be it will png format.
Take a screen shot of a specif area and save as variable
