Join Michele Vallisneri for an in-depth discussion in this video ✓ Challenge: functional fractal, part of Python: Programming Efficiently.
(reverberating cymbal)…- [Instructor] For your challenge,…I'm giving you a procedural function…that draws a fractal tree using recursion.…This is very similar to what we did…to draw the Koch snowflake.…Let me demonstrate.…Import everything, execute my function definitions,…and do the tree.…At every level of recursion except the lowest one,…the Turtle moves forwards, calls itself, then moves back.…
At the lowest level, the procedure calls a new method fb…that I've given to Turtle which moves forward and then back.…This is used to draw the terminal branches only.…Your task will be to rewrite this procedural function…in a functional style that acts on a sequence of steps,…much as we did for fun Koch…in the video on functional programming.…
