How does the turtle work(pixels and angles)?[discuss + experiment]

import turtle

import random

grumble = turtle.Turtle()

grumble.speed(5) # 1:slowest, 3:slow, 5:normal, 10:fast, 0:fastest

# SQUARE CODE

def square():

  for i in range(4):

    grumble.forward(30)

    grumble.right(90)

# TRIANGLE CODE

def triangle():

  for i in range(3):

    grumble.forward(30)

    grumble.right(120)

# CIRCLE CODE

def circle():

  for i in range(360):

    grumble.forward(1)

    grumble.right(1)

# CIRCLE OF SQUARES

def circle_of_square():

  for i in range(5):

    square()

    grumble.right(36)

    triangle()

    grumble.right(36)

# CIRCLE OF TRIANGLES

for i in range(100):

  circle_of_square()

  grumble.setx(random.randint(-200, 200))

  grumble.sety(random.randint(-200, 200))
