[Python] How to parse JSON string?

Problem
I plan to connect to a url, http://od.moi.gov.tw/api/v1/rest/datastore/A01010000C-000628-023, to get data with JSON format. How to parse JSON string vi Python, and get specific data?

How-to
Here has sample code:

import urllib.request, json
from test.json.row import row

import os
os.environ['http_proxy'] = 'http://proxy.cht.com.tw:8080'

with urllib.request.urlopen("http://od.moi.gov.tw/api/v1/rest/datastore/A01010000C-000628-023") as url:
    # return with dict data type
    data = json.loads(url.read().decode())
    dataList = []
    count = 1
    # 取得 result / records 下的資料
    for value in data['result']['records']:
        # Skip the first record
        if(count > 1):
            no = value['No']              # 編號
            address = value['Address']    # 地點位置
            deptNm = value['DeptNm']      # 管轄警察局
            branchNm = value['BranchNm']  # 分局
            dataList.append(row(no, address, deptNm, branchNm)) 
            print('no={}, address={}, deptNm={}, branchNm={}'.format(no, address, deptNm, branchNm))
        count += count
