Python argparse module is the preferred way to parse command line arguments. It provides a lot of option such as positional arguments, default value for arguments, help message, specifying data type of argument etc. At the very simplest form, we can use it like below. import argparse parser ...

每多一个参数,代码中就会多一行parser.add_argument,手写每个参数的配置时会很繁琐,如名称需要加--,还有修改默认值,类型以及描述的时候很麻烦,最后也会导致自己的代码很冗长,维护不便。 就算用了更高级一点的Click,也需要不停的写option, 而且有几个option对应函数就要写几个输入参数与之匹配,写代码实在是繁琐,比如...
command1_parser.add_argument("arg1", type=int, help="Argument 1 for command 1")使用add_argument()方法添加一个选项，传入选项的名称、类型和帮助信息。6、定义命令处理程序：为每个命令定义一个处理程序函数，该函数将执行与命令相关的操作。defcommand1_handler(args): print(f"Executing command1 with ...
