time.sleep(5) This means you want the script to delay 5 seconds before continuing. The sleep function also accepts floats if you want to give a more precise number: time.sleep(1.75) This will sleep for 1 second and 750 milliseconds. You can also use a float to delay for less than a...
Python time sleep function is used to add delay in the execution of a program. We can use python sleep function to halt the execution of the program for given time in seconds. Notice that python time sleep function actually stops the execution of current thread only, not the whole program....
sleep(0.1) # Pause for 1/10 of a second. 接下来,我们将程序的其余部分放在一个 try 语句中。当用户在 Python 程序运行时按下CTRL-C时,Python 会引发KeyboardInterrupt异常。如果没有try - except语句来捕捉这个异常,程序就会崩溃,并显示一条难看的错误消息。然而,对于我们的程序,我们希望它通过调用sys.exit...

比如time.sleep(1) 大概是这样实现的: { Py_BEGIN_ALLOW_THREADS(释放GIL) sleep(1); Py_END_ALLOW_THREADS(申请GIL) } 即通过两个宏来实现阻塞调度,注意阻塞调度则不会重置 PyEval_EvalFrameEx 内的 _Py_Ticker 为 初始值 _Py_CheckInterval。
