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。 通过使用...

You may write an infinite loop eitherintentionallyorunintentionally. Intentional infinite loops are powerful tools commonly used in programs that need to run continuously until an external condition is met, such as game loops, server processes, and event-driven apps like GUI apps or asynchronous code...
You’ll typically use and find comparison operators in Boolean contexts like conditional statements and while loops. They allow you to make decisions and define a program’s control flow.The comparison operators work on several types of operands, such as numbers, strings, tuples, and lists. In...
The loops, functions, and conditions in Python have to be properly indented. Example: Python 1 2 3 4 5 6 # Defining a function with proper indentation def course(): print("Intellipaat is a best platform for Upskilling!") course()# Calling the function course() Output: Explanation:...
Running a Python while loop on a game board Another frequent use for Python while loops is moving pieces in boardgames. If you want to make sure to cover all fields, you’ll need two loops embedded in each other. But be sure to pay attention to the runtime. Under certain circumstances...
