I am a newbie on the programming world and I am trying to learn Python as it is the easiest and very strong programming language. I've learnt all basic theories and the programming syntax and then I have solved some problems from urionlinejudge. Now I'am trying to learn GUI Appliations and I am trying to learn Tkinter module of Python.
Previously I posted a Restaurant Management System GUI application that I made with Python and Tkinter module of python. Here is Phonebook GUI Application Made With Python and Tkinter. I will post the code into different parts. This is the first part.
There are six different sections and I separated them into six different python files. Sections are : Home, My People, About Us, Add People, Update People, Display People and there is also a feature to delete peoples.
Let us jump to the codes of the Homepage. I named the file "main.py".
Importing
import tkinter as tk
import _sqlite3
from tkinter import PhotoImage, messagebox
import datetime
from add_people import Add_people
from update_people import Update_people
from display import Display_people
date = datetime.datetime.now().date()
date = str(date)
con = _sqlite3.connect('database.db')
cur = con.cursor()
I've added the other files in the import section but not posting those files now because the blog will be large. After posting all the parts you can run the codes.
