import time while True: print("This is an infinite loop with a delay.") time.sleep(1) # 延时1秒 (可选)提供一个退出循环的机制,如捕获特定键盘中断或设置某个条件来跳出循环: 捕获键盘中断(Ctrl+C): python try: while True: print("Press Ctrl+C to exit the loop.") time.sleep(1) except...
loop_thread = threading.Thread(target=infinite_loop) loop_thread.start() time.sleep(5) # 主线程等待5秒 stop_loop() loop_thread.join() print("循环已中断") 在这个例子中,infinite_loop函数在一个单独的线程中运行,通过修改全局变量running的值来中断循环。 2. 使用进程 from multiprocessing import Pro...
while True in Python creates an infinite loop that continues until a break statement or external interruption occurs. Python lacks a built-in do-while loop, but you can emulate it using a while True loop with a break statement for conditional termination.With...

time.sleep(1) Run Code Output 01:47:43 PM 01:47:44 PM 01:47:45 PM 01:47:46 PM ... ... ... In the above example, we obtain and print the current local time inside an infinitewhile loop. Then, the program waits for1second before repeating the same process. ...
在 _loop_writing中,调用了 self._loop._proactor.send(self._sock, data)生成了一个写操作的 future。而 _proactor,也就是在 ProactorEventLoop里的IocpProactor实例了。 class IocpProactor: def send(self, conn, buf, flags=0): self._register_with_iocp(conn) ov = _overlapped.Overlapped(NULL)...
Breaking Infinite LoopsThis example shows how break safely exits an otherwise infinite loop. infinite_break.py import time start = time.time() while True: print("Processing...") time.sleep(1) if time.time() - start > 5: print("Timeout reached") break ...
Summary Function send_document throws NameError: name 'file' is not defined in when wait_till_finished=True and silent=False. When wait_till_finished=True and silent=True it falls into an infinite loop instead. I can see, that on master ...
