[Tutor] request to run program on a Linux machine

[Nick Lunt]

Hi Gregor,

very cool. Im a complete python beginner so I'll use your code as a
tutorial ;).

Anyway, I just ran it on Linux with python on a 700Mhz pc with 256Mb RAM
and there's no performance issues at all.

Im running python 2.3-3mdk with Tkinter 2.3-3mdk .

I put the speed down to 1 and quit the program while a disc was moving
and got the following error in the console:

$ ./hanoi.py 
Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__
    return self.func(*args)
  File "./hanoi.py", line 216, in step
    if self.hEngine.step():
  File "./hanoi.py", line 127, in step
    self.HG.next()
  File "./hanoi.py", line 70, in hanoi
    for x in self.hanoi(n-1, src, temp, dest): yield None
  File "./hanoi.py", line 70, in hanoi
    for x in self.hanoi(n-1, src, temp, dest): yield None
  File "./hanoi.py", line 70, in hanoi
    for x in self.hanoi(n-1, src, temp, dest): yield None
  File "./hanoi.py", line 71, in hanoi
    yield self.move(src, dest)
  File "./hanoi.py", line 84, in move
    disc.move_to(x2,y2, self.speed)
  File "./hanoi.py", line 30, in move_to
    self.cv.move(self.item,dx,dy)
  File "/usr/lib/python2.3/lib-tk/Tkinter.py", line 2162, in move
    self.tk.call((self._w, 'move') + args)
TclError: invalid command name ".1078258988"
$

Cheers
Nick.
