Let's Play Darts
The dart board challenge on trinket.io is a nice challenge where anyone can follow along. It helps to give you a glimpse at the power and precision behind the Python programming language, without any prerequisite knowledge of programming. It is also a great way for a beginner to relax and have fun while messing around with Python commands.
The dart board challenge uses Turtle. You can learn more about the PythonTurtle environment here.
If you would like to try out the challenge for yourself then head on over to the Bullseye Challenge.
