python中list中的元素为字典,对字典中value相同的进行分组

hosts_nodes为一个list中的元素为字典

argparse的用法

x.py
if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument("--kvmparams",default='params.json', help="path for test source")
    args = parser.parse_args()
    with open(args.kvmparams, 'r') as f:
        key_info = json.loads(f.read())
    Main(key_info).start()

shell 下调用
python x.py --kvmparams params.json
