为什么在另一个线程中使用“getstr”时该线程会暂停？ Python 诅咒

Question

I have made a thread that is supposed to show the seconds passing. Unfortunately, when I use getstr from the curses module the whole script stops, including the thread. I have to use a thread lock to stop random characters being printed out because of overlapping orders.

Any suggestions on how to fix this or an alternative would be great!

In the below example window and window2 are already set-up...

lock = threaing.Lock()


def main_function():
  #starts thread
  t1 = threading.Thread(target=time_calc,args=(window2,))
  t1.start()
  #Gets user input
  while True:
    data = window1.addstr(y,x,"Type something in!")
    data = window1.getstr(y,x,5)

    lock.acquire()
    window1.erase()
    txt = "You said: "+data

    window1.addstr(y,x,txt)
    lock.release()


def time_calc(window2):
  current_count = 0

  while True:

    time += 1

    text = "Time Count: "+str(time)

    lock.acquire()
    window2.erase()

    window2.addstr(y,x,text)
    lock.release()

    time.sleep(1)

The problem with my code

I figured out the problem with my code. You can't run a thread inside a thread for some reason and I originally had my main function called to be considered a thread. I guess I should have stated this in my question. Sorry

There is probably a way to run a thread in a thread, but this did not work for me.

My Updated Code

lock = threading.Lock()

def call_threads():
  t1 = threading.Thread(target=main_function,args=(window1,))
  t1.start()

  t2 = threading.Thread(target=time_calc,args=(window2,))
  t1.start()

def main_function(window1):
  #Gets user input
  while True:
    data = window1.addstr(y,x,"Type something in!")
    data = window1.getstr(y,x,5)

    lock.acquire()
    window1.erase()
    txt = "You said: "+data

    window1.addstr(y,x,txt)
    lock.release()


def time_calc(window2):
  current_count = 0

  while True:

    time += 1

    text = "Time Count: "+str(time)

    lock.acquire()
    window2.erase()

    window2.addstr(y,x,text)
    lock.release()

    time.sleep(1)
