Drawing the French tricolour with Python

You can create images using python. The first tutorial Python:Flags Tutorial 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. Using the PYX library you can use methods such as fill together with path.rect to create simple images.

The PyX library used here has coordinates with (0,0) in the botton left corner.

• Each rectangle is 1 wide and 2 high

.

def drawFlag(g): g.fill(path.rect( 0,0,50,100),[color.rgb.blue]) g.fill(path.rect( 50,0,50,100),[color.rgb.white]) g.fill(path.rect(100,0,50,100),[color.rgb.red])
