![]() Moreover, we’ve defined the MINIMUM_BRANCH_LENGTH (in pixels), which sets the minimum threshold to create further sub-branches. angle: the angles from which the sub-branches emerge from the parent branch.shorten_by: determines by how many pixels the sub-branches will be shorter than the parent branch.branch_length: the current length of the branch in pixels.We’ve also defined the signature of our recursive function, which will be the following: We’ve then made it face upwards with setheading(). We’ve imported turtle and created an instance of turtle.Turtle(), which will be the object moving around the canvas and drawing our tree. In order to create a tree, we are going to divide each branch into two sub-branches (left and right) and shorten the new sub-branches, until we reach a minimum branch length, defined by ourselves: import turtle MINIMUM_BRANCH_LENGTH = 5 def build_tree(t, branch_length, shorten_by, angle): pass tree = turtle.Turtle() tree.hideturtle() theading(90) lor('green') build_tree(tree, 50, 5, 30) turtle.mainloop() In this post, we’ll be drawing both a fractal tree and a Koch snowflake. ![]() Moreover, we’ll be using turtle to draw the fractals. ![]() Now, how can we build a fractal in Python? Given that we are repeating a structure at different scales, we’ll need to apply a recursive solution. Or, as defined by Benoit Mandelbrot, “a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole”. First of all, what is a geometric fractal? A geometric fractal is a geometric shape with a repeating structure at different scales: it doesn’t matter whether you get closer to the image or not, you’ll always see the same pattern.
