网络爬虫：使用pymysql进行数据库交互

import pymysql
 mysql_client =pymysql.Connect('127.0.0.1','root','18603503110','1712B',3306,charset='utf8')
    # 创建游标(执行mysql语句)
    cursor = mysql_client.cursor()
sql = """
    INSERT INTO ...(%s)
    VALUE (%s)
    """%(','.join(dict.keys()),','.join(['%s']*len(dict)))
    try:
        cursor.execute(sql,list(dict.values()))
        mysql_client.commit()
    except Exception as err:
        print(err)
        mysql_client.rollback()
