Hey I am trying to have a loop be pausable from user input like having a input box in the terminal that if you type pause it will pause the loop and then if you type start it will start again.
Something like this but having the '#Do something' continually happening without waiting for the input to be sent.
while True:
#Do something
pause = input('Pause or play:')
if pause == 'Pause':
#Paused
Ok I get it now, here is a solution with Threads:
from threading import Thread
import time
paused = "play"
def loop():
global paused
while not (paused == "pause"):
print("do some")
time.sleep(3)
def interrupt():
global paused
paused = input('pause or play:')
if __name__ == "__main__":
thread2 = Thread(target = interrupt, args = [])
thread = Thread(target = loop, args = [])
thread.start()
thread2.start()
You can't directly, as input
blocks everything until it returns.
The _thread
module, though, can help you with that:
import _thread
def input_thread(checker):
while True:
text = input()
if text == 'Pause':
checker.append(True)
break
else:
print('Unknown input: "{}"'.format(text))
def do_stuff():
checker = []
_thread.start_new_thread(input_thread, (checker,))
counter = 0
while not checker:
counter += 1
return counter
print(do_stuff())
