import pymysql 
d_mysql = {
    'host': '127.0.0.1',    
    'port': 33333,
    'user': '*****',
    'password': '*****',
    'db': '*****',
    'charset': 'utf8'
    }
conn = pymysql.connect(**d_mysql)
cur = conn.cursor()
data = ('jack', '2', '0', '0')
insert_ = "insert into qsbk_massege (username, fans, scandal, comment) values (%s, %s, %s, %s);"
cur.execute(insert_ % (data[0], data[1], data[2], data[3]))
