piano keys waveform

how can I show the waveform when I press the button?

Python:

from tkinter import*

pygame.init()

root .title("Music box")
root. geometry("1352x700+0+0")
root .configure(background = 'white')


ABC = Frame(root, bg = "powder blue",bd = 20, relief = RIDGE)
ABC.grid()
ABC1 = Frame(root, bg = "powder blue",bd = 20, relief = RIDGE)
ABC1.grid()
ABC2 = Frame(root, bg = "powder blue", relief = RIDGE)
ABC2.grid()
ABC3 = Frame(root, bg = "powder blue", relief = RIDGE)
ABC3.grid()

strl = StringVar()
strl.set("Just Like Music")
Date1 = StringVar()
Time1 = StringVar()

Date1.set(time.strftime("%d/%m/%Y"))
Time1.set(time.strftime("%H:%M:%S"))

The waveform played is not within the code, it looks like the code instructs a laptop to play a note from .wav files.
The waveform is stored in the laptop that the program is associated with.
You could run an audio software package on the laptop and examine the .wav files directly.

I mean what code should I use so that when I pressed a button it will also show the output waveform?

If the processor is fast enough you could use the analogue to digital input and use the serial plot function within the arduino Ide, you'd need to do some fudging to slow down the sample rate so's not to make a display that scrolls too fast.
