將爬取數據寫入MySQL數據庫

import urllib.request
import requests
import pymysql#鏈接數據庫的包
from lxml import etree

db=pymysql.connect('localhost','dsuser','badpassword','dsdb')#地址，用戶，密碼，數據庫名
print('success')
cur=db.cursor()#創建遊標
cur.execute('DROP TABLE IF EXISTS pk')
sql='CREATE TABLE pk(title varchar(50))'#創建數據表
cur.execute(sql)
print('建立成功')
url='https://www.51job.com/'
response=requests.get(url)
response.encoding='gbk'
html=etree.HTML(response.text)
title=html.xpath('//div[@class="cn hlist"]//a/span/text()')
for i in range(len(title)):
    sqle='INSERT INTO pk(title) VALUES(%s)'#插入語句
    value=(title[i])
    cur.execute(sqle,value)
    db.commit()#提交數據庫
cur.close()
