Argparse is more than just a module for parsing command-line arguments. It’s a foundation upon which you can build powerful command-line applications in Python. When you master argparse, you’re not just learning how to parse command-line arguments — you’re also learning the basics of how...

ArgumentParser 通过parse_args() 方法解析参数。它将检查命令行,把每个参数转换为适当的类型然后调用相应的操作。在大多数情况下,这意味着一个简单的 Namespace 对象将从命令行参数中解析出的属性构建: >>> >>> parser.parse_args(['--sum', '7', '-1', '42']) Namespace(accumulate=<built-in function...
args = parser.parse_args() main(args.EVIDENCE_FILE, args.IMAGE_TYPE, args.CSV_REPORT) main()函数处理与证据文件的必要交互,以识别和提供任何用于处理的$I文件。要访问证据文件,必须提供容器的路径和图像类型。这将启动TSKUtil实例,我们使用它来搜索图像中的文件和文件夹。要找到$I文件,我们在tsk_util实例...
