Drawing a Circle of Nested Decagons with Python Turtle: Recursive Fractal Art

This code uses the turtle module to draw a circle of nested decagons recursively. It starts by setting up the turtle screen and defining three functions: draw_decagon, draw_decagon_circle, and draw_decagon_circle_recursive.

The draw_decagon function takes four arguments: x and y for the position of the decagon, length for the length of its sides, direction for the direction it is facing, and color for its color. It uses the turtle module to draw the decagon at the given position, with the given length, direction, and color.

The draw_decagon_circle function takes three arguments: radius for the radius of the circle of decagons, direction for the starting direction of the circle, and n for the number of decagons in the circle. It calculates the length of the sides of the decagons based on the radius and the number of decagons, and then uses a loop to draw each decagon in the circle at the appropriate position.

The draw_decagon_circle_recursive function takes the same three arguments as draw_decagon_circle, but it also includes a recursive call to itself. It first calls draw_decagon_circle to draw the outermost circle of decagons, and then calculates the radius of the next circle based on the current radius and the number of decagons. It then recursively calls itself with the new radius and direction to draw the next circle of nested decagons.

Finally, the code calls draw_decagon_circle_recursive with the initial radius, direction, and number of decagons to draw the entire nested circle of decagons.

The resulting image is a beautiful pattern of nested decagons in various colors, with smaller and smaller decagons nested within each other.
