Answer 1

import turtle
loadWindow = turtle.Screen()
turtle.speed(1)
turtle.colormode(255)
turtle.pensize(1)

STEP = 25
LENGTH = 1000
for i in range(0, LENGTH, STEP):
   turtle.penup()
   turtle.setpos(-LENGTH/2, LENGTH/2 - i)
   turtle.pendown()
   turtle.setpos(LENGTH/2, LENGTH/2 - i)
   turtle.penup()
   turtle.setpos(-LENGTH/2 + i, LENGTH/2)
   turtle.pendown()
   turtle.setpos(-LENGTH/2 + i, -LENGTH/2)
