# This example uses a prewritten library (or module) called turtle.
# A library is a collection of code, written and compiled by someone else,
# that is ready for you to use in your program
#
# Reference: https://docs.python.org/3/library/turtle.html


import turtle
# [style convention: leave 2 blank lines after import statement(s)]

duh = turtle.Turtle()    # create an instance of a turtle, named "duh"
duh.forward(50)          # duh initially starts facing right, tell dur to move forward 50 pixel
turtle.done()            # leave the screen (try comment it out, run and observe what happens)
# [style convention: leave a blank line at the end of program]
