#26974 — Threading KeyError in Python 3.3 beta 2?

I thought I would try out Python 3.3 beta 2.  

This works well so far but I keep getting the message:

Exception KeyError: KeyError(6308,) in <module 'threading' 
    from 'c:\\Program Files\\Python33\\lib\\threading.py'> ignored

after some of my python code completes.  

Is this an issue worth reporting?

It might be, but it depends on what your code is and is doing. Can you
put together a minimal test case?

===========
Thank you for your response.

Here is a fairly short bit of code which produces the exception:

for pre in ('12', '13', '14', '15', '21' ):
  n = int(pre + '543')
  s = str(n * n)
  if len(set(s)) == 9:
    print(n, s)

Um, I don't think so. 


>>> for pre in ('12', '13', '14', '15', '21' ):
...   n = int(pre + '543')
...   s = str(n * n)
...   if len(set(s)) == 9:
...     print(n, s)

Since your code doesn't even import threading, let alone use it, I can't 
imagine how you get an error in threading.

Hey, I try not to get scornful until at least the sixth post :)

Interesting. I just downloaded a clean 3.3 onto this Windows box,
saved your script to a file ("booom.py" hehe), and ran it - no
exception. Same thing pasting that code into the interactive
interpreter or idle. Did you import anything before running that code?
If not, it may be a site.py problem or something.

===============
Thanks to you both for your responses.

Its an IDE issue of some kind (I am using WING).

When I run under a command prompt (or IDLE) all is well.

Sorry to have bothered you.

Next time, do mention that sort of environmental consideration in the
original post :)

As a general rule, be careful of threading and windowing toolkits;
quite a few of them have restrictions on what you can and can't do, or
even completely do not support threads.
