How to Create Nested Heptagons using Python Turtle Graphics смотреть онлайн

This is a Python program that uses the turtle module to draw a recursive circle of heptagons. The heptagons are drawn using the draw_heptagon() function, which takes a position, length, direction, and color as parameters. The draw_heptagon_circle() function is used to draw a circle of heptagons, given a radius, direction, and number of heptagons. Finally, the draw_heptagon_circle_recursive() function is used to recursively draw a circle of heptagons, decreasing the radius with each recursion until the base case is met (when the radius is less than 10).

The program starts by initializing the turtle screen, setting its title and dimensions, and hiding the turtle. The turtle speed is set to 0 (fastest) and the screen tracer is set to 0 to update the screen only after each shape is drawn.

The program then defines the draw_heptagon() function, which takes a position (x, y), length, direction, and color as parameters. It uses turtle's goto() and seth() methods to move the turtle to the starting point of the heptagon and set its heading. The color of the turtle is set using the colorsys module's hsv_to_rgb() method, which takes a color in HSV format and returns its RGB equivalent. Finally, the heptagon is drawn using a for loop that repeats 7 times, moving the turtle forward by the length of each side and turning left by the angle of each vertex.

The draw_heptagon_circle() function is then defined, which takes a radius, direction, and number of heptagons as parameters. It calculates the length of each heptagon's side based on the radius and number of heptagons, and then uses a for loop to draw each heptagon by calling the draw_heptagon() function with the appropriate position, length, direction, and color.

Finally, the draw_heptagon_circle_recursive() function is defined, which takes a radius, direction, and number of heptagons as parameters. It first checks if the base case has been met (if the radius is less than 10), in which case it stops the recursion. Otherwise, it calls the draw_heptagon_circle() function to draw a circle of heptagons with the current radius, direction, and number of heptagons. It then calculates the radius of the circle for the next level of recursion and calls the draw_heptagon_circle_recursive() function with the new radius and direction (which is incremented by 180 degrees divided by the number of heptagons).

Finally, the draw_heptagon_circle_recursive() function is called with initial parameters, and the turtle screen is updated and the window is kept open until the user closes it.
