首先要pip install pymysql
import pymysql,sys
#print(sys.path)
from settings import mysql_info
# sql='insert into user (username,password) VALUE ("haha","man")'
# sql2='select * from user limit 3'
def OpMysql(host,port,user,passwd,db,charset,sql):
conn = pymysql.connect(host=host, port=port, user=user, passwd=passwd, db=db,charset=charset)
# 执行SQL，并返回收影响行数
#effect_row = cursor.execute("update students set name = 'niuhy' where id = 1;")
# 创建游标
cur = conn.cursor(cursor=pymysql.cursors.DictCursor)#返回字典
#cur = conn.cursor()#返回元组tuple,元组不可修改
cur.execute(sql)
if sql.startswith('select'):#判断是什么语句
res = cur.fetchall()
else:
conn.commit()
res = 88
cur.close()
conn.close()
return res
def jude_username(username):
pass
#@judge_username
def login():
username = input('set your username: ')
pass
#OpMysql(mysql_info['host'],mysql_info['port'],mysql_info['user'],mysql_info['passwd'],mysql_info['db'],mysql_info['charset'],sql2)
#if __name__=='__main__':
