找不到错误,就是无法修改图片名称

老师关了一次电脑之后运行不出来了呢，docker ps也找不到了呢？

IDEA自带的Terminal用起来很方便

照视频里教的打1L*money*(years)，报错了是哪里有问题吗

老师，我的记事本的编码，没有unicode，这怎么设置

老师，我这个情况怎么办？

老师，为什么我用mybatisx生成的注释比视频的少啊？

老师这个是怎么回事啊？主键删除不了，用语句也不行

代码:

import pymysql

connection = pymysql.connect(host="localhost",user="root",password="123456",db="test06",charset='utf8')

cursor = connection.cursor()

sql = "insert into emp(empno,ename) values(%s,%s)"

args=(1234,'marry')

count = cursor.execute(sql,args)

print("count:",count)

connection.commit()

报错:

请问哪里出错了

老师，我这个pycharm怎么无法设置解释器

就是说 教学视频与资料内容很多都对不上啊  有些资料还缺 就是说能不能走点心

报了一个路径错误的问题，这个getRealPath是获取的那个地方的路径？

请问老师左边的s1是在栈中的变量引用右边堆中的对象嘛?然后那个type为什么是Student而不是class,还是老师的意思是指Student class?
