You need to post your _exact_ code. I had to change: from queue import Queue into from Queue import Queue So: _do_ you have a "queue" (lowercase) module? Is it buggy? Let's pretend not. Using the standard Queue module I can't reproduce your problem and your code looks correct to my eye. However, it is possible that the output stream used by print() is not thread safe. In which case your multiple outputs may stem from output buffer mishandling and not from your thread pool. Make another Queue to receice items, change _worker() to .put(item) onto it and collect form the queue and print in the program's main code. That way only one thread (the main one) will be trying to print(), removing the possibility of mismanagement of the output if print() is not thread safe.
