Yes. In fact, it's a tuple. Maybe, I'll change it for just printing the
second item of it.
Thanks a lot.

Ok, sorry about the above question. I solved it adding this to the main
thread:
try:
SrvrTCP = module.ThreadedTCPServer(ip,port)
SrvrTCP.start()
except Exception, description:
MsgBox(self,"TCPServer
Error:\n\n"+str(description),title="TCPServer",style=wx.OK |
wx.ICON_ERROR)
return

Excellent. That makes it pretty easy then, since even though you are
spawning a thread to do the work, your main thread isn't expected to
continue processing in pa

I'd like to catch *just after* the .start() call.

Doing it properly needs a language extension.

Definitely a better architecture. Anyway, one supported way for

How
Nevermind. I found a better solution. I used shared memory to create
a keep-alive flag. I then use the select function with a specified
timeout, and recheck the keep-alive flag after each timeout.
Thanx for all the input.

Here's a dumbed down version of what i'm doing:
import time
import threading
class threader(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
pass
def run(self):
try:
while 1:
time.sleep(5)
except SystemExit

What _is_ the problem? We're still waiting for a clear description from
the OP as to what the problem really is. How would you describe what
_your_ problem is?

I also need an answer to this problem. I'm using windows. Throwing an
exception in thread B from thread A using a callback function.
The function runs, but the thread never actually catches the exception.
The try/except block is in the run() method (over-riden from the
Thread class)

Define what "get" means for your purposes. It appears that you mean you
want to catch the exception, but in the thread which launched the other
thread in the first place. If that's true, please
Thanks for your answer, but I think that created thread in python
should create a thread either on windows and linux.
Can you give me Python example of how to do what I want to do? Thanks

Threads can share the same memory space.
Hence a very neat way to achieve the objective.

On non-Windows system there are a ton of ways to do it--this is almost a
whole field unto itself. :) (D-BUS, fifos, sockets, shmfs, etc.) In
Windows, I wouldn't have a clue.
I guess this is a hard question to answer without a bit more
information. :)

Hi all,
How can I get a raised exception from other thread that is in an
imported module?
For example:
---
programA.py
---
import programB
thread = programB.MakeThread()
thread.start()
---
programB.py
---
import threading, time
class SomeExcept
