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

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

742277203 发表于 2018-5-10 10:39:34

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？
