Problems inserting two different classes within the same frame into a notebook using Tkinter and Python
问题 I have been trying inserting two different classes (in the code below "MyListbox" and "Calculation") within the same frame into a notebook using Tkinter and Python. Actually I Have not received any report from my computer saying where I am wrong. My computer doesn't show anything, not even a message. Can you help me solving this problem? Thanks in advance. Here is the code: import Tkinter from Tkinter import * from Tkinter import Tk, Text, BOTH, W, N, E, S from ttk import Frame, Button, Label
