Programming Homework Help

I’m working on a project that would detect the motion of the hands that show on the camera. For example, if I want to say “Hi”, I would just move my hand in front of the laptop camera and the camera should detect the motion and translate the movement to a written word that shows “Hi”. I need this to be written in Python. I just need 4-5 movements that would be translated from movements to English words. Please feel free to use Open Sources but I need the link of the open sources that you would use along with the editing that u did from the open sources. Please ask me anything if you are confused about anything or you have any question.
