In python, how do I end the countdown when I have input

Question

Description: now, I have done input and countdown, both of which are carried out at the same time, but I want to achieve like this:

When I don't input anything during the countdown, it will execute another function after the countdown
When I input something before the end of the countdown, the countdown will pause, and then another function will be executed

My code is as follows：

import time
from threading import Thread


def waitinput():

    wait_input_str = input("Please enter your account：\n")
    print(wait_input_str)


thd = Thread(target=waitinput)
thd.daemon = True
thd.start()
for i in reversed(range(1, 11)):
    print("\rcountdown:{}second".format(i), end="")
    time.sleep(1)
# ###########################################

You can use isAlive() method to check if your thread has terminated.

In your case:

import time
from threading import Thread


def waitinput():

    wait_input_str = input("Please enter your account：\n")
    print(wait_input_str)


thd = Thread(target=waitinput)
thd.daemon = True
thd.start()
for i in reversed(range(1, 11)):
    if not thd.isAlive():
        # Execute 2
        print("\nCountdown has stopped")
        break
    print("\rcountdown:{}second".format(i), end="")
    time.sleep(1)

if thd.isAlive():
    # Execute 1
    print("\nCountdown has ended")
