I have a few questions regarding the SDK of Mavic 2 Pro and Phantom 4 V2. Because when I do my searching in DJI developer official website for windows SDK, there is only C++ / C programming language ( I know this from sample code of windows SDK at github). So,

1) Is there any SDK for these drones using python programming language?
2) Does this SDK can be developed in Linux/Ubuntu ?
3) If the SDK is available in python, what python version will it be? Is it version 2.7 or 3.5+ or both ?

As far as I know, there is no SDK that uses python as a programming language.
Onboard SDK supports developed in Linux/Ubuntu. But it doesn't support Mavic 2 and Phantom 4.

Only the Tello supports python programming:

Otherwise I can confirm ever thing that the above user Hajar Anis said!
