How manim create a Polyrhythms Visualization ainmation | with source code

This article records how I created a Polyrhythms Visualization ainmation using manim.

the video is requiring below a few items.

1. it is pattern 3:4:5:6:7:8:9:10
2. sound effect is seperated from here. I presented source code ONLY
3. I wrote the below code when I am starting to learn manim, code is not gracefully at all. it is ONLY for your reference.

from manim import *
from os import system
import random
import os
config.frame_width  = 16
config.frame_height = 9
config.frame_size = (1920,1080)#(1080,1920)#(3840,2160)#(2560,1440)#(1920,1080)#
config.frame_rate = 30
config.background_color = BLACK

            index = 0
            for x in list:
                if x == num:
                    return index
                index = index + 1
            return -1

                               radius=1.5, stroke_opacity=2) #.scale(scale_factor)
            if t%2 == 1:
