Answer 1

You can use the threading library, there is such an entity as event. Using event, you can send a signal to all threads, and threads receiving this signal can either suspend or self-destruct.

Answer 2

1) The easiest way to do this is using the multiprocessing library.
2) Something like this:

code

import multiprocessing 
import time 

def func(number): 
  for i in range(1, 10): 
    time.sleep(0.01) 
    print('Processing ' + str(number) + ': prints ' + str(number*i)) 

# list of all processes, so that they can be killed afterwards 
all_processes = [] 

for i in range(0, 3): 
  process = multiprocessing.Process(target=func, args=(i,)) 
  process.start() 
  all_processes.append(process) 

# kill all processes after 0.03s 
time.sleep(0.03) 
for process in all_processes: 
  process.terminate()
