Made some structures with turtle library.
import turtle
window = turtle.Screen()
window.bgcolor("lightgreen")
ak= turtle.Turtle()
ak.color("blue")
ak.shape("turtle")
distance=5
ak.up()
for i in range(30): #Starts with 5, and go by 2
ak.stamp() #Leaves an expression on the canvas
ak.forward(distance)
ak.right(20)
distance= distance+4
window.exitonclick()
import turtle
n= int(input(': '))
def fib(n):
a, b= 0,1
for _ in range(n):
for _ in range(4):
turtle.forward(a)
turtle.left(90)
x,y = turtle.pos()
turtle.penup()
turtle.goto(x+a,y)
turtle.pendown()
a,b = b, a+b
screen= turtle.Screen()
t=turtle.Turtle()
t.speed(0)
fib(n)
screen.exitonclick()
mport turtle
wn = turtle.Screen()
wn.bgcolor("black")
bob = turtle.Turtle()
bob.color("white")
bob.speed(100)
for i in range(700):
bob.forward(1.5*i)
bob.right(90.5)
wn.exitonclick()
