Parsing command-line arguments We have a program here calledadd.pythat uses Python'sargparsemodule to parse two arguments,xandy: importargparseparser=argparse.ArgumentParser()parser.add_argument('x',type=float)parser.add_argument('y',type=float)args=parser.parse_args()print(args.x+args.y) ...
我们来分析下这段代码,首先就是创建一个参数解析对象赋给parser,然后在parser对象中使用add_argument方法添加参数以及各种选项,其中--test就是参数,这个参数的名称依其作用自定义,type=str指定输入值类型为字符串,default='China'是默认值,就是说如果不指定参数,就显示China这个默认值 对于parser.parse_args()解析参数...
