python3连接mysql

1. 安装PyMysql;

2.mac版如下:

 1 # -*- 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()
