# Draw a Sunflower in Python Using Turtle


# import math and turtle

    phi = angle * (math.pi / 180.0)
   
    for i in range (numseeds + numpetals):
      # figure out the next x, y position
      r = cspread * math.sqrt(i)
      theta = i * phi
      x = r * math.cos(theta)
      y = r * math.sin(theta)

      # move the turtle and orient it correctly
      t.penup()
      t.goto(x, y)
      t.setheading(i * angle)
      t.pendown()

      if i <  numseeds:
