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...
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...
async def infinite_loop(): while True: print(True) await asyncio.sleep(1) asyncio.run(infinite_loop()) 细节解释: 异步函数:使用async def定义异步函数infinite_loop,并在循环中使用await关键字等待异步操作完成。 异步运行:通过调用asyncio.run()方法运行异步函数,使其在事件循环中执行无限循环。 实际应用: ...
time.sleep(2.4) suspends execution for 2.4 seconds. "Printed after 2.4 seconds" is printed. Create a Digital Clock in Python import time while True: # get current local time as structured data current_time = time.localtime() # format the time in 12-hour clock with AM/PM formatted_time ...
第二章,“Analyzing Network Traffic with Scapy”,介绍了一个数据包操作工具 Scapy,它允许用户嗅探、创建、发送和分析数据包。本章提供了使用 Scapy 进行网络流量调查、解析 DNS 流量、数据包嗅探、数据包注入和被动 OS 指纹识别的见解。这使您能够在网络上创建和发送自定义数据包,并分析各种协议的原始输出。
五、龙之境 原文:inventwithpython.com/invent4thed/chapter5.html 译者:飞龙 协议:CC BY-NC-SA 4.0 本章中您将创建的游戏名为龙之境。玩家需要在两个洞穴之间做出选择,这两个洞穴分别藏有宝藏和一定的厄运。 …
asyncdefnever_ending_task():whileTrue:awaitasyncio.sleep(1)asyncdefmain_infinite_await():awaitnever_ending_task()# 这将无限期运行asyncio.run(main_infinite_await()) 错误使用asyncio.gather:忘记等待asyncio.gather()意味着调用函数不会等待计划的任务完成。
Exploring InfinitewhileLoops Sometimes, you might write awhileloop that doesn’t naturally terminate. A loop with this behavior is commonly known as aninfinite loop, although the name isn’t quite accurate because, in the end, you’ll have to terminate the loop somehow. ...
Set reasonable blocking or sleep in the business code to ensure that low-priority tasks can be scheduled normally. For necessary loops, add safety measures. For example, add a loop counter in the loop body so that even if an infinite loop occurs, it can exit when the loop reaches a certa...
while True: # The main program loop. print(' ' * indent, end='') print('***') time.sleep(0.1) # Pause for 1/10 of a second. Next, we place the rest of the program inside a try statement. When the user presses CTRL-C while a Python program is running, Python raises the...
