分享一个错误案例：如果将程序的名字命名为tkinter.py，在pycharm里运行时会报错 AttributeError: module 'tkinter' has no attribute 'Tk'
解决方案：修改文件名。

这里好像有点问题，等于是pack()后再赋值给了w了，似乎应该如下写哈

1. v = StringVar()
   
2. w = Label(master,textvariable = v)
   
3. w.pack()
   
4. v.set("~新的文本~")

求助：我这个计算器在按数字的过程中，label1、label2的显示数字不会变化？？？

为什么entry组件没有get   delete   insert  这些方法啦

小甲鱼，请问一下，最后事件循环的时候使用root.mainloop()还是tkinter.mainloop()呢？
