主線clock迴圈等支線改變running狀態

• from threading import Thread
• from time import ctime,sleep
• running = True
• def func():
•     global running
•     input()
•     running = False
•     sleep(3)
• thread = Thread(target = func)
• thread.start()
• while running:
•     print(ctime() , end = "\\r")
•     sleep(1)
• print("clock stopped")
• thread.join()
• print("thread joined")
