Out of boredom and fun, the installation of turtle module, p3 installation may be a problem, as follows :

Solution:

Instructions on turtle module functions, a lot of online search, the following comments are very detailed, I will not say more, go directly demo below:

See the little turtles yet, it is that the figure above the arrow, ha ha
