给sleep（）的值是5，希望代码执行在执行时延迟5秒.time.sleep(5)下面是一个示例代码：import time print("Welcome to guru99 Python Tutorials")time.sleep(5)print("This message will be printed after a wait of 5 seconds")输出：Welcome to guru99 Python Tutorials This message will be printed after ...
print(f"{seconds} seconds have passed") async def main(): await wait_for_seconds(3) # 等待3秒 print("Main coroutine finished") if __name__ == "__main__": asyncio.run(main()) # 运行协程 5、使用循环和条件变量: 如果您的程序是一个多进程或多线程程序,可以使用循环和条件变量来实现等待...
python wait用法 在Python中，有几种方法可以实现等待：1. time.sleep(seconds)：该函数会让程序暂停指定的秒数，然后继续执行后续代码。例如，`time.sleep(5)`会暂停程序5秒。```python import time print("开始")time.sleep(3)print("结束")```2. threading模块：该模块提供了多线程编程的支持，可以使用`...
