Preface

最近刚开始学习用python 的时候遇到一个对于我这样的新手来说比较棘手的问题. 我查询了好久, 大多数给出的答案就是代码写错了 而且是不给错误行数的那种.😵‍💫

查询了很久都没找到一个靠谱的解决方案, 干脆自己来排除哪里的问题; 我就一个一个代码块的去试毒, 果然被我找到了. 原来是 tkinter 在捣鬼

然后我又开始查询各种 tkinter 的用法, 确实找到不少, 但是都不能解决问题,
因为他们的教程都只是这这几行

from tkinter import *
import tkinter * as tk# 然后还有这两行
root = tk.Tk()
root.withdraw()

我觉得我也妹写错啊, 尝试各种方式没有解决. 我就跑去官网看文档;

解决方法

这是官方的文档

问题1:

对比了一下, 唯一的区别就是, 我把代码放到了。startup 里面 官网例子在 外面放着

于是我就改用了官网的写法, 把 tk 初始化放在了 class 外面, 果然把问题解决了;

除了这个问题外还要注意一个问题;

问题2: tk.Tk() 这里的 Tk 的 k 是小写

错误信息 并没有什么实际作用/提示
