Stop Iteration Error

[quest]

If you want to pass it you need to say what the program has to do when there are no more items in the sequence

try:
    tq, q = next(self.incoming)
except StopIteration:
    # No more items in self.incoming --> what to do here?

You can also catch the exception at higher level in the calling stack.

this time I am in a never endless loop...

I will think and try something and will let you know..
Thanks
