There is no Python interface yet. An alternative to the old Picamera, imaginatively named Picamera2, is in development. This too will integrate much more directly with established Python libraries to access things like windowing and graphics functions. Picamera2 will be developed by Raspberry Pi (unlike Picamera itself, which is actually third-party code), and this will facilitate both support and continuing future development.
