Extract audio from video in python

Question

I am trying to extract the audio file from a video file and save it to a wav file and then again combine the audio and video together in python3. I have found many tutorials using ffmpeg but I don't want to use any external tool to do the task. It will be helpful if someone gives me any suggestion on how to do it in python. Thank you.
