Hi Dick, just to show you a bit of the versatility of the new turtle module I've prepared to tiny rectangle-generator program examples.
They intentionally use different programming styles and also turtle graphics techniques different from the ones you used to accomplish something similar to what you did, of course in a very simplified way and without your eleborated user interface and colormanagement. ----------- Version 1: procedural, using stamp() ----------- from turtle import * from random import random, randint from time import sleep MAXLEN = 30 MAXWID = 25 def randomcolor(): return random(), random(), random() reset() title("Python turtle graphics: random rectangle generator") hideturtle() resizemode("user") shape("square") for cycle in range(randint(3, 5)): bgcolor(randomcolor()) for rect in range(randint(5,10)): shapesize(3 + random()*MAXLEN, 3 + random()*MAXWID, randint(3, 10)) color(randomcolor(), randomcolor()) stamp() sleep(0.5) sleep(1) clearstamps() ----------- Version 2: object oriented, uses a list of turtles, which change their properties (size, color, visibility) ----------- from turtle import Screen, Turtle from random import random, randint from time import sleep MAXLEN = 30 MAXWID = 25 def randomcolor(): return random(), random(), random() class RectGenerator(object): def __init__(self): self.s = s = Screen() s.reset() s.title("Python turtle graphics: random rectangle generator") self.rectturtles = [] for n in range(10): t = Turtle(visible=False) t.hideturtle() t.resizemode("user") t.shape("square") self.rectturtles.append(t) def run(self): for cycle in range(randint(3, 5)): self.s.bgcolor(randomcolor()) n = randint(5,10) for index in range(n): t = self.rectturtles[index] t.shapesize(3 + random()*MAXLEN, 3 + random()*MAXWID, randint(3, 10)) t.color(randomcolor(), randomcolor()) t.showturtle() sleep(0.5) sleep(1) for t in self.s.turtles(): t.hideturtle() if __name__ == "__main__": rg = RectGenerator() rg.run() Hope you like it Gregor _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
