选择一个好的驾校，用数据说话，我用python

在交管局网站上，看到每月的考试信息都有工具。
想想，可以汇总下，按照考试人数排个名（群众的选择大部分时候都是有道理的）

1.数据先抓取下来

#encoding=utf8
import urllib
import urllib.request
import http.cookiejar
from bs4 import BeautifulSoup
# 导入SQLite驱动:
import sqlite3

User_Agent = 'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0'
header = {}
header['User-Agent'] = User_Agent


vyear='201601'
urlFile = urllib.request.urlopen('https://sn.122.gov.cn/publicitypage?size=20&fzjg=%E9%99%95A&page=1&tjyf='+vyear)
data = urlFile.read()
urlFile.close()
data = data.decode('utf-8',errors='ignore')
print("get page success")
pre = "<div id='pagination'><span  class=''>共"
index1 = data.find(pre) + len(pre)
index2 = data.find('条记录', index1)

ebi=data[index1 : index2];
print("总条数:"+ebi)

totalPage="";
if (int(data[index1 : index2]))%20>0:
    totalPage=str(int(int(data[index1 : index2])/20+1)) 
else:
    totalPage=str(int(int(data[index1 : index2])/20))
print("totalpage:"+totalPage);


def getList(pageId):

    hosturl = 'https://sn.122.gov.cn/publicitypage?size=20&fzjg=%E9%99%95A&tjyf='+vyear+'&page='+pageId
    print("getcontent:"+hosturl);

    request = urllib.request.Request(hosturl, None, header)
    response = urllib.request.urlopen(request)
    htmldata = response.read()
    soup = BeautifulSoup(htmldata,"html.parser")
    trs = soup.findAll('tr')
    for x in range(1,len(trs)):
        tr = trs[x]
        tds = tr.findAll("td")
        savejiaxiao(tds[0].contents[0],tds[1].contents[0],tds[2].contents[0],tds[3].contents[0],tds[4].contents[0],tds[5].contents[0]);

def savejiaxiao(t_date, t_name,t1,t2,t3,t4):
    conn = sqlite3.connect('jiaxiao.db')
    cursor = conn.cursor()
    # 执行一条SQL语句，创建user表:
    cursor.execute('create table IF NOT EXISTS kaoshi (id INTEGER PRIMARY KEY, t_date varchar(100),t_name varchar(100),t1 varchar(100),t2 varchar(100),t3 varchar(100),t4 varchar(100) )')
    cursor.execute('select * from kaoshi where t_date=\''+t_date+'\' and t_name=\''+t_name+'\'  and t1=\''+t1+'\' and t2=\''+t2+'\' and t3=\''+t3+'\'  and t4=\''+t4+'\' ')
    values=cursor.fetchall()
    if len(values) > 0:#以前就存在
        print('已经存在:'+t_date+','+t_name)
    else:
        try:
            cursor.execute('insert into kaoshi (t_date, t_name,t1,t2,t3,t4) values(?,?,?,?,?,?)',(t_date,t_name,t1,t2,t3,t4)) 
            print("save success."+t_date+','+t_name)
        except Exception  as e:
            print('except:', e)


# 关闭Cursor:
    cursor.close()
# 提交事务:
    conn.commit()
# 关闭Connection:
    conn.close()        

for x in range(1,int(totalPage)+1): #代表从1到totalPage+1(不包含totalPage)
    errorLink=[]
    try:
        getList(str(x))
    except Exception  as e:
        print('except:', e)
        errorLink.append(x)
print("errorLink:"+str(errorLink));

2.把数据导出到excel里

# -*- coding:utf-8 -*-
import xlwt

# 导入SQLite驱动:
import sqlite3


def export():
    conn = sqlite3.connect('jiaxiao2016.db')
    cursor = conn.cursor()
    cursor.execute('select * from kaoshi')
    values = cursor.fetchall()
    i=0
    book=xlwt.Workbook()
    sheet1=book.add_sheet('驾校')
    for line in values:
        row = sheet1.row(i)
        row.write(0,line[0])#id
        row.write(1,line[1])#title
        row.write(2,line[2])#link
        row.write(3,line[3])
        row.write(4,line[4])
        row.write(5,line[5])
        row.write(6,line[6])
        sheet1.col(1).width = 5000
        i=i+1  
    book.save('驾校2016.xls')  
    cursor.close()
    conn.commit()
    conn.close()


export()

3.在excel里做个透视图，按月汇总并排序下，得到结果如下
