python 3.x - python3 concurrent.futures how to stop a threadPool -


hope there way i'm looking :

i have python3 concurrent.futures threadpoolexecutor object. multi threading used send lot of http requests concurrently.

i able stop entire pool of threads (having threads stop working) when keyboardinterrupt exception caught. basically, program can summed following piece of code :

import time,concurrent.futures  def waitprint() :     time.sleep(1)     print("working ..")     return true  future_results = [] executor = concurrent.futures.threadpoolexecutor(max_workers=4) in range(0,100) :     future_results.append(executor.submit(waitprint))  try :     future in concurrent.futures.as_completed(future_results) :         print(future.result()) except keyboardinterrupt :     print("stopped user")     executor.shutdown(wait=false)  print("finished")

i thought executor.shutdown function have stopped pool , associated threads it's not case, when hit ctrl+c, hundred threads still created writing down "working ..." in terminal...

is there way me stop execution of threads before launched ?

thanks help, more info program : github.com/almandin/fuxploider

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
