背景：主机较多，要添加的聚合图形也很多，通过python3来批量新增

代码如下：#!/bin/env pythonimport json

import urllib.request
import argparse
import re
import requests
import sys

re_digits = re.compile(r'(\d+)')

def emb_numbers(s):
    pieces=re_digits.split(s)
    pieces[1::2]=map(int,pieces[1::2])
    return pieces

def sort_strings_with_emb_numbers2(alist):
    return sorted(alist, key=emb_numbers)

def requestjson(url, values):
    head = {'Content-Type': 'application/json-rpc'}
    request_auth = requests.post(url,headers=head,data=json.dumps(values))

    output = request_auth.json()
    return output


def authenticate(url, username, password):
    values = {'jsonrpc': '2.0',
              'method': 'user.login',
              'params': {
                  'user': username,
                  'password': password
              },
              'id': '1',
              'auth': None
    }
    output = requestjson(url, values)
    return output['result']


#通过主机组获取对应主机名，并按照主机名排序，保证新增聚合图形按照主机名字排序
def gethosts(groupname, url, auth):
    host_list = {}
