Drawing the French tricolour with Python

You can create images using Java. The first tutorial Flags looks at drawing flags of the world, from simple flags such as Libya to more complicated flags such as the Stars and Stripes of the USA. In Java you can use methods such as setColor and fillRect to create simple images.
