python3连接mysql

1. 安装PyMysql；

2.mac版如下：

# -*- coding: utf-8 -*-
import pymysql
# 密码我用*打马赛克啦 哇哈哈
conn = pymysql.connect(host = '127.0.0.1', unix_socket = '/tmp/mysql.sock', user = 'root' , password = '******', db = 'mysql', charset = 'utf8s')
cur = conn.cursor()
cur.execute("USE mysql")

cur.execute("select * from user")
print(cur.fetchone())
cur.close()
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；

# -*- coding: utf-8 -*-
import pymysql

conn = pymysql.connect(host = 'XXXXXX', port = 1234, user = '****' , password = '*****', db = 'xxxx', charset = 'utf8')
cur = conn.cursor()
cur.execute("USE xxxx")

cur.execute("SELECT * from  xxxx where id = 1039")
print(cur.fetchone())
cur.close()
conn.close()
