カメを正方形の特定の領域に重ねるにはどうすればよいですか？

だから私は学校とのプロジェクトのためにカメに精通しなければなりませんでした。私は基本的に、正方形を重ねること以外に、教授が求めたすべてのものを手に入れました。

しかし、彼は正方形がこのように重なることを望んでいます

私はこれをまったく再現することができませんでした。それらは、簡単に解決するためにコードに投入する必要があるものかどうか疑問に思っています。

これが私のコードです

import turtle #Imports the 'turtle module' which allows intricate shapes and pictures to be drawn
my_turtle_pos = (10 , 10)
def square(my_turtle,x,y,length) : #I set up a function that helps me determine the square

    my_turtle.penup() #Picks 'up' the turtle pen
    my_turtle.setposition(x-length/2,y-length/2) #Helps set positon
    my_turtle.pendown() #Puts 'down' the turtle pen
    my_turtle.color('black','red') #Allows black outline, with red filling
    my_turtle.begin_fill() #Starts the filling of red and helps remember the starting point for a filled area
    my_turtle.forward(length) #Moves the turtle by the specified amount 'length'
    my_turtle.left(90) #Moves the turtle by given amount '90'
    my_turtle.forward(length)
    my_turtle.left(90)
    my_turtle.forward(length)
    my_turtle.left(90)
    my_turtle.forward(length)
    my_turtle.left(90)
    my_turtle.end_fill() #Stops filling with red, which will close with the current color

def graphic_pattern(my_turtle,x,y,length,times): #recursive function
    if times <= 0:  #This just tells us how many 'times' it needs to repeat till given amount
        return
    newSize = length/2.2 #This will grab the new size
    graphic_pattern(my_turtle,x-length/2,y-length/2,newSize,times-1) #Functions to help with writing 'smaller' squares
    graphic_pattern(my_turtle,x-length/2,y+length/2,newSize,times-1)
    graphic_pattern(my_turtle,x+length/2,y-length/2,newSize,times-1)
    graphic_pattern(my_turtle,x+length/2,y+length/2,newSize,times-1)
    square(my_turtle,x,y,length)


my_turtle = turtle.Turtle(shape="arrow") #You can use differen't shapes for the turtle, I chose arrow, though the turtle was cool :)
my_turtle.speed(100) #I am not sure how fast the turtle can go, I just chose 100 cause it went by quicker.

graphic_pattern(my_turtle,3,0,300,4) #Example pattern stated from homework assignment.

ペンが最初に正方形を描くところと関係があると思います。ご入力いただきありがとうございます。
