turtle is a pre-installed Python library that enables users to create pictures and shapes by providing them with a virtual canvas. The onscreen pen that you use for drawing is called the turtle and this is what gives the library its name.

import turtle
from turtle import *
import random


speed(speed = 'fastest')


def draw(n, x, angle):
    for i in range(n):
        colormode(255)
        a = random.randint(0, 255)
        b = random.randint(0, 255)
        c = random.randint(0, 255)

        pencolor(a, b, c)
        fillcolor(a, b, c)
        begin_fill()

        for j in range(5):
            forward(5 * n - 5 * i)
            right(x)
            forward(5*n - 5*i)
            right(75 - x)

        end_fill()
        rt(angle)
