How is this different from regular ol' 'len' ?
It's better, because len() can't overflow the stack. ;)

As Laurent posted, it's simply a literal double-quote character,
enclosed in single quotes. But for making a quoted string, this isn't

Hello
I've a list of tasks to perform. Each of them is a threading.Thread.
Basically I have :
while task_list :
task = task_list[0]
task.run()
task_list.remove(task)
Now I want, in some circumstance to raise errors that make the loop stop.
In order IOError to make stop the loop
I read the library documentation. I think that if I get a trick to kill
a thread, then I'm done.
Is there a way ?
