Python sys module stores the command line arguments into a list, we can access it using. This is very useful and simple way to read command line arguments as String. Let’s look at a simple example to read and print command line arguments using python sys module. Below image illustrates t...

在Python 编程中,我们经常需要处理运行参数(command line arguments),比如从命令行传递一些信息给我们的程序。Python 提供了非常方便的模块来帮助我们处理这些参数,其中argparse是最为常用的库之一。本文将探讨如何使用argparse来处理多行的运行参数,并附带示例代码。
