Using Python

10.32 The Lvy curves are fractal graphical patterns that can be defined recursively. Like the Koch curves, for every nonnegative integer n > 0, the Lvy curve Ln can be defined in terms of Lvy curve Ln1; Lvy curve L0 is just a straight line. Figure 10.17 shows the Lvy curve L8. (a) Find more information about the Lvy curve online and use it to implement recursive function levy() that takes a nonnegative integer n and returns turtle instructions encoded with letters L, R and, F, where L means rotate left 45 degrees, R means rotate right 90 degrees, and F means go forward. >>> levy(0) 'F' Lvy curve L8. >>> levy(1) 'LFRFL' >>> levy(2) 'LLFRFLRLFRFLL' (b) Implement function drawLevy()) so that it takes nonnegative integer n as input and draws the Lvy curve Ln using instructions obtained from function levy().
