        page:this.data.num
      },
      success:res=>{
        console.log(res.data);
        if(res.data.status==200){
          console.log(res.data.data.result)
          this.setData({
            list:res.data.data.result,
            isshow:true
          })
          console.log(that.data.list)
        }

老师，咱们之前辛辛苦苦学那么多知识点，结果这一个软件全部解决，那学习mybatis映射文件如何拼接sql语句这些知识点有必要牢记吗？我们之前写的持久层，业务层，控制器层，是不是到后期都是用框架了，如果都使用框架了，那咱们之前学的也是必须牢记吗？

from tkinter import *
from tkinter import messagebox

root=Tk()

    messagebox.showinfo("Message","送你一朵玫瑰花")

老师，我这里使用import.reload(),怎么无法识别我创建好的模块呢

这些坐标用的都是阿里云的还是国外的？？？？

import copy

a=[90,80,[6,7]]
b=copy.copy(a)

print("a",a)
print("b",b)

b.append(70)
b[2].append(8)

print("a",a)
print("b",b)

为什么不对呀？

为什么运行错误呀？

a=[,,[,]]
b=copy.copy(a)

(,a)
(,b)

b.append()
b[].append()

(,a)
(,b)
