# This program was written to demonstrate that choosing a random number
# between 2 and 12 is NOT the same as choosing two random numbers
# between 1 and 6 and adding them (like dice)

import turtle
import random

# This list of turtles will draw the columns of the histogram
tList = []
numbins = 13
for i in range(numbins):
  # Each time round the loop we'll create a new turtle
  ## Create a turtle called nt
  
  ## Put the turtle's pen up
  
  # Each turtle has a different position on the baseline
  nt.goto(i*15-100, -150) # All start on same baseline
  
  ## Put the turtle's pen down
  
  ## Set the turtle's heading to point upwards (90 degrees)
  
  ## Set the turtle's pen size to 4
  
  ## Set the turtle's colour to red
  
  ## Set the turtle's speed to 10
  
  ## Add the new turtle to the list tList
  
  
for i in range(1000):
  ## Get a random integer in the range 0 to 12 (use random.randint())
  
  ## Use the random number to select the appropriate turtle
  ## from the tList amd move it forwards 2 steps

## ------------------------------------------------------
## When you have this working, change the line that generates the
## random number to generate two random numbers in the range 0 to 6
## and add them together. What happens to the shape of the histogram?
