How to get .wav volume in timecode?

Question

Python

1. you need to find out the length of the .wav (I can easily do it myself, but it's better to use the same one as the rest)
2. get the volume of the sound on the time code n

#psevdo code
file = open("audio.wav")
print(file.getvolume(123)) # вернет значения от 0-100 или еще в каком то диапазоне.
file.close()
