while True:
    try:
        run_script()  # May raise TryAgain
        break
    except TryAgain:
        pass


If you prefer to only retry a finite number of times:


for i in range(10):
    try:
        run_script()  # May raise TryAgain
        break
    except TryAgain:
        pass
else:
    # break skips past the for...else block
    raise GiveUpError('too many failures')
"

Hi,

Thanks for the ideas, I haven't tried them yet.

I wonder if they will work in a multi-threaded fashion.

I doubt it.

The run_script runs in it's own thread.

The exception would have to be raise from another thread. (The other thread 
check for errors and needs to abort the run script).

I doubt thread B can interrupt thread A via exceptions/exception handling 
?!?

Bye,
  Skybuck.
