# @File:插入数据.py
# @Software:PyCharm

import pymysql

con = pymysql.connect(host='localhost',user='root',password='123456',database='python_db',port=3366)
# 创建游标对象
cur = con.cursor()
# 编写插入数据的sql
sql = 'insert into t_student(sname,age,score) values(％s,％s,％s)'
try:
 # 执行sql
 cur.executemany(sql,[('小楚',21,99.9),('小刘',20,59),('小朱',20,85),('小宋',22,95)])
 # 提交事务
 con.commit()
 print('插入成功')
except Exception as e:
 print(e)
 con.rollback()
 print('插入失败')
finally:
 con.close()

结果

然后到Navicat for MySQL中验证
