Creating Nested Nonagons using Python Turtle Graphics

This is a Python code for drawing nested nonagons using the turtle graphics library. The program defines three functions: draw_nonagon(), draw_nonagon_circle(), and draw_nonagon_circle_recursive().

draw_nonagon() takes five parameters: x and y are the coordinates of the center of the nonagon, length is the length of each side of the nonagon, direction is the initial direction of the turtle (the heading), and color is the color of the nonagon. The function first lifts the turtle pen up, then moves the turtle to the starting point of the nonagon using the given coordinates and direction. It sets the turtle color to the given color, and puts the pen down. It then uses a for loop to repeat the drawing of each side of the nonagon by moving forward by the specified length and turning left by 40 degrees.

draw_nonagon_circle() takes three parameters: radius is the radius of the circle of nonagons to be drawn, direction is the initial direction of the turtle (the heading), and n is the number of nonagons in the circle. The function calculates the length of each nonagon side based on the radius and the number of sides, then uses a for loop to repeat the drawing of each nonagon in the circle by calling draw_nonagon() with the appropriate parameters. It updates the direction for each nonagon using the formula direction += 360 / n, which evenly distributes the nonagons around the circle.
