本文采用Python3进行语法编写，Python3与Python2中的函数会有所不同，但是相差不大，具体的问题可以百度找到，因有朋友在做汽车方面的业务，因此需要一些网络数据进行支撑，一个个找会非常的繁琐，因此之前弄了些爬虫数据。这里进行其中一部分爬虫的代码共享。
爬虫效果如下：
首先要定义一些常量
# !/usr/bin/env python
# -*- coding:utf-8 -*-
# by Zason_Zhang
import urllib,urllib.request,json
from pyquery import PyQuery as pq
class Constant():
"""常量"""
NAME = 'name'
DIANMIAN = 'dianmian'
ADDRESS = 'address'
TELEPHONE = 'tel'进行爬虫爬取
