# 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()
