Loudness is a perceptual quality of audio related nonlinearly to the audio
waveform. You can approximate it quite well by squaring the time domain
waveform, summing the result and taking the logarithm (cube root can also
work here). If you are interested in rough perceptual loudness per second,
that will do if you sum over 1 second segments of your audio.

the amplitude of the waveform is the loudness. So to measure the loudness every 0.1 seconds you get the amplitude at that point in time. Maybe you want something else?
this project uses scipy and that returns a numpy array (https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.wavfile.read.html#scipy.io.wavfile.read) so you'd just seek in that np array to the time you're interested in and return the value at that time.
