PYTHON HELP. I can't figure out the code.

The Spirograph toy included a ruler shape (as well as circles). The edge of the ruler could be defined by straight linesy=dspanning the range 0 < x < L. The ruler is then L long and 2dwide. At the end of the ruler there are semicircles, radius d, which connect the two lines. Make two additional spriographs, with different ratios of L:d, using the ruler as the fixed object. The two plots should be combined into a single figure using the subplot() module.
