坐在电脑前运行程序是没问题的,但让程序在没有你直接监督的情况下运行也很有用。您计算机的时钟可以安排程序在某个指定的时间和日期或定期运行代码。例如,你的程序可以每小时抓取一个网站来检查变化,或者在你睡觉的时候在凌晨 4 点执行一个 CPU 密集型的任务。Python 的time和datetime模块提供了这些功能。
Using Start and Stop Parameters list_numbers=[1,2,3,4,5,6,7,8,9,10]element=7list_numbers.index(element,5,8) So the syntax is:list_name.index(element, start, stop). Here thestartandstopvalues are optional. In fact, only use it when entirely sure about the range; otherwise, you ...
