I want to make this picture with a turtleneck.

I would like to create the diagram below using the for, while, if syntax, but I don't understand the code very well.Could you please let me know?

A 2x2 grid line is drawn like a rice field, and an equilateral triangle line is drawn from each midpoint of the four sides on the outer periphery.

The code I wrote looks like the one below.

import turtle def draw4square(t,size):
    for i in range (4):
        for i in range (3):
            t.forward (size)
            t.left(90)
        t.forward (size)

I think there are several ways to write it, but I will start by correcting the comments you wrote.
I think the following is a fragment of the code you gave me in the comment.

def draw4square(t,size):
    for i in range (4):
        for i in range (3):
            t.forward (size)
            t.left(90)
            t.forward (size)

"From the figure to the point where I noticed ""4 loops"", it was good, but I think it was difficult to control the direction of the turtle."

There are three modifications to the code.

def draw4square(t,size):
    # Unused subscripts (i) are accepted with _
    for_in range(4):
        # There are four sides, so you have to forward four times to write a square.
        for_in range(4):
            t.forward (size)
            t.left(90)
        # square once and turn
        t.left(90)

However, the red triangle in the figure seems stronger than the square.If you look at only one square and a triangle, you will be able to write a stroke, so let's draw this all at once.

import turtle

def draw_triangle(t,size):
    # a triangular drawing of three sides
    for correct in (-30, 120, 120):
        t.right(rect)
        t.forward (size)

    # to put something back in its original direction
    t.right (150)

def draw4pieces(t,size):
    t.pensize(3)
    t. begin_fill()

    for_in range(4):
        # Only one side of the square is drawn first.
        t.color('blue','green')
        t.forward (size)

        # At the end of the line, a triangle is drawn instead of a red pen.The size is appropriate.
        t.color('red','green')
        draw_triangle(t,size*1.5)

        # Finally, it returns to the origin of the triangle, so it draws the rest of the square.
        t.color('blue','green')
        for_in range(3):
            t.right (90)
            t.forward (size)

        # When the turtle returned, it turned right from the beginning.
        # It's 90 degrees lying down, so it's OK!

t=turtle.Turtle()
draw4pieces(t,100)
t.end_fill()
US>turtle.done()
