How to use the webbrowser module to open a webpage in Python 3.x

Overview
When developing Python applications, sometimes we need to open a webpage to display some information or user interface. In order to achieve this function, Python provides the webbrowser module, which allows us to open a specified web page in the default browser. This article will introduce in detail how to use the webbrowser module to open a web page in Python 3.x. The following are the detailed steps:
