作爲 Apple Store App 獨立開發者,你要搞限時促銷,爲你的應用生成200個激活碼(或者優惠券),並將生成的激活碼(或者優惠券)保存到 MySQL 關係型數據庫中。python
def getrand(): while True: a=random.randint(48,122) if a<=57 or (a>=65 and a<=90) or (a>=97 and a<=122): break return a if __name__=='__main__': import random import pymysql array=[] for k in range (200): rand='' for i in range(6): rand=rand+chr(getrand()) array.append(rand) conn=pymysql.connect(host='127.0.0.1',port=3306,user='root',passwd='',db='mysql') cur=conn.cursor() cur.execute('create table if not exists juan (ma varchar(20))') cur.executemany("insert into juan values(%s)",array) cur.close() conn.commit() conn.close()
使用的是python3.5版本的。。。mysql
