time.sleep(timedelta(seconds=3, milliseconds=450)) 3、使用线程休眠: 如果您的程序是一个多线程程序,可以使用threading.Event对象来让一个线程等待另一个线程完成其任务,创建一个threading.Event对象,并将其传递给需要等待的线程,在需要等待的线程中,调用event.wait()方法,在完成线程的任务后,调用event.set()方法...
DateTime 模块确定脚本的执行时间 此解决方案测量 Wall time,即总运行时间,而不是 CPU 时间。import datetimeimport time# get the start datetimest = datetime.datetime.now()# main program# find sum to first 1 million numberssum_x = 0for i in range(1000000): sum_x += i# wait for 3 sec...
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 a wait of 5 seconds 如何使用sleep()延迟执行?下面的示例定义display()函数。 display()函数将显示一条消息“ Welcome to Guru99 Tutorials”。 调用该函数...
When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). As join() always returns None, you must call isAlive() after join() to decide whether a timeout happened -- if the thread ...
