2019.05.31(am): How to draw a spiral out of squares with python turtle

Today I used a Python Turtle to draw a square spiral.

Below is a picture of the drawing. Yesterday I used Python for the base, because I forgot to develop Python in a virtual environment. So today I did not forget to activate the virtual environment.

code

import turtle
size=1
while (True):
  turtle.forward(size)
  turtle.right(91)
  size = size + 1
