I've got a question based off an answer I saw. It uses a thread pool to manage threads but each thread prints 'Going to sleep... i', sleeps for i time and then prints 'Slept..'. my question is why it prints 'Going to sleep...Going to sleep...Going to sleep...'? It doesn't print them on a newline unless I explicitly add \n to the end of the string. Here is my output without the \n. ` Going to sleep...Going to sleep...Going to sleep... Slept ..0 Going to sleep... Slept ..1 Going to sleep... Slept ..2 Slept ..3 Slept ..4 done!!` Here is my output with the newline Going to sleep... Going to sleep... Going to sleep... Slept ..0 Going to sleep... Slept ..1 Going to sleep... Slept ..2 Slept ..3 Slept ..4 done!! The spaces between Going to sleep... and the first Slept.. seem strange to me as well. Here's the code import time from multiprocessing.dummy import Pool def run(i): print "Going to sleep...\n" time.sleep(i) print ("Slept .." + str(i)) p = Pool(3) res = [p.apply_async(run, (i,)) for i in range(5)] p.close() p.join() print "done!!"
