Python对MYSQL数据库的操作

通过引入pymysql来操作数据库:

# -*- coding: UTF-8 -*-
import pymysql
import pymysql.cursors

connection = pymysql.connect(host='127.0.0.1',
                             user='root',
                             password='',
                             db='test',
                             port=3306,
                             charset='utf8')  # 注意是utf8不是utf-8
try:
    with connection.cursor() as cursor:
        sql_1 = 'select * from user'
        cout_1 = cursor.execute(sql_1)
        print("数量： " + str(cout_1))
        for row in cursor.fetchall():
            print("user_name:", str(row[0]), 'python_time', str(row[1]))

        sql_2 = 'insert into user(user_name,time) value("python_name","python_time")'
        cout_2 = cursor.execute(sql_2)
        print("数量： " + str(cout_2))
        connection.commit()
finally:
    connection.close()
