import pymysql

from pymysql.cursors import DictCursor
while True:

        break
    conn = pymysql.connect(host='127.0.0.1',port=3306,user='root',password='123456',charset='utf8',database='moms')
    cursor = conn.cursor(cursor = DictCursor)
    sql = "select  * from class_demo where name = %s"
    cursor.execute(sql,["展示"])
    data = cursor.fetchall()
