Based on your error messages there is a file is called random.py so it tries to import it rather than the standard library version... Try renaming your file to something more descriptive of what makes it different from the library version. > tk = Tk() > > canvas = Canvas(tk, width=400, height=400) > canvas.pack() > > > def random_randrange(height): > pass > > > def random_randrange(width): > pass These two functions are the same since Python doesn't understand the parameter names it just sees def aFunctionName(aParameterName) so the second def simply overwrites the first. What you really mean (I think) is def random_randrange(aNumber): pass Although that's still not a very descriptive name... > def random_rectangle(width, height): > x1 = random_randrange(width) > y1 = random_randrange(height) > x2 = x1 + random.randrange(width) > y2 = y1 + random.randrange(height) > canvas.create_rectangle(x1, y1, x2, y2) > random_rectangle(400, 400) You call this same function recursively, this will result in an infinite loop until you run out of memory. I don't know what you are trying to do but this is surely not it. This function never gets called and, since its not assigned as an event handler, it will never be executed. > tk.mainloop() > Here are the error messages: > > Traceback (most recent call last): > File "/Users/lwaters/PycharmProjects/tkinternew/rectangles.py", line > 2, in <module> > import random > File "/Users/lwaters/PycharmProjects/tkinternew/random.py", line 17, > in <module> > randomRects(100) Notice the two files listed above are in the same folder and one is called random.py -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
