python3连接mysql

# -*- coding: utf-8 -*- 2 import pymysql 3 # 密码我用*打马赛克啦 哇哈哈 4 conn = pymysql.connect(host = ‘127.0.0.1‘, unix_socket = ‘/tmp/mysql.sock‘, user = ‘root‘ , password = ‘******‘, db = ‘mysql‘, charset = ‘utf8s‘) 5 cur = conn.cursor() 6 cur.execute("USE mysql") 7 8 cur.execute("select * from user") 9 print(cur.fetchone()) 10 cur.close() 11 conn.close()

3. windows版如下：

注意事项：1.port后面写int而不是str；

　　　　　2.添加charset=‘utf8‘以保证查出的中文字符能正常显示；

 1 # -*- coding: utf-8 -*-
 2 import pymysql
 3 
 4 conn = pymysql.connect(host = ‘XXXXXX‘, port = 1234, user = ‘****‘ , password = ‘*****‘, db = ‘xxxx‘, charset = ‘utf8‘)
 5 cur = conn.cursor()
 6 cur.execute("USE xxxx")
 7 
 8 cur.execute("SELECT * from  xxxx where id = 1039")
 9 print(cur.fetchone())
10 cur.close()
11 conn.close()
