I have a loop while that ends only when I press the q key, then the program quits. Within this loop , at a certain time or condition, I start a thread that takes a few 10 seconds to execute.
My problem is, if I exit the loop by pressing q with a running thread , it is canceled.
I would like the loop / script to wait for the thread to run, and then end the program. Is that possible?
Thank you.
In addition to the mentioned by Felipe Avelar using the method Thread.is_alive() , there is also the method Thread.join() . Both can be used together.
When Thread.join() is called, it tells the thread to wait for a given thread to finish before the main thread proceeds and executes the next statement. Here is an example:
import time, threading
def fun():
for i in range(5):
time.sleep(1)
print(i)
def main():
thread = threading.Thread(target=fun)
thread.start()
thread.join()
# A thread foi finalizada, fazer algo a partir daqui
print("Thread finalizada")
main()
