At the top level, the script uses a function drawFractalLine to draw three fractal lines. Each line is specified by a given distance, direction (angle), and level: The initial angles are 0, -120, and 120 degrees. The initial distance can be any size, such as 200 pixels. If the level is 0, then the turtle moves the given distance in the given direction. Otherwise, the function draws four fractal lines with ⅓ of the given distance, angles that produce the given effect, and the given level minus 1. The function drawFractalLine is recursive. Write a script that draws the Koch snowflake. Define a function main that will draw a Koch snowflake with the following parameters when the program is run: Width = 200 Height = 200 Size = 150 Level = 4

import turtle

def drawFractalLine(t, distance, angle, level):
  if level == 0:
    t.forward(distance)
  else:
    drawFractalLine(t, distance / 3, angle, level - 1)
    t.left(angle)
    drawFractalLine(t, distance / 3, angle, level - 1)
    t.right(2 * angle)
    drawFractalLine(t, distance / 3, angle, level - 1)
    t.left(angle)
    drawFractalLine(t, distance / 3, angle, level - 1)
