Contact Management System Project in Python

About Contact Management System in Python

Hello everyone, welcome to copyassignment.com. In this tutorial, we are going to learn about the Contact Management System Project in Python programming language. We are making use of the Tkinter module for creating the GUI- based project of contact management system project in python with source code. Hence making it easy to understand and use.

In this system, we are performing all the operations of adding, viewing, deleting, and updating contact lists. This GUI-based Contact Management system in Python provides the simplest management of contact details. This project mainly focuses on the CRUD operations of the database management system. To run this project, you need to install python on your PC first. This GUI-based project is designed for all python beginners.

So let’s get started with the project

Code flow: Contact Management System in python with source code

Importing the libraries

#Importing the modules
import tkinter
import tkinter.ttk as ttk
from tkinter import *
import sqlite3
import tkinter.messagebox as tkMessageBox

Explanation:

The import function includes these modules in the project

These modules are used for the following purposes:

1. Tkinter – To create the GUI.
2. SQLite3 – To connect the program to the database and store information in it.
3.Tkinter.messagebox – To show a display box, displaying some information or an error or warning
6. Tkinter.ttk – To create the tree where all the information will be displayed.

Declaring the variables for the contact management system python program

# Variables required for storing the values
f_name = StringVar()
m_name = StringVar()
l_name = StringVar()
age = StringVar()
home_address = StringVar()
gender = StringVar()
phone_number = StringVar()

Explanation:

Here we are declaring the variables to accept the values in the string format while filling in the details.

Code for exit function of a system

#Function for exiting the system
def Exit():
    O = tkinter.messagebox.askyesno("Contact Management System", "Do you want to exit the system")
    if O > 0:
        root.destroy()
    return

Explanation:

In the above code, we are defining the exit function where the user is about to take some action to which, the user is to answer yes or no. If yes it will close the GUI else if no then it will return back to the main display of the contact management system in python.

Output:

Resetting the values in the system

#Function for resetting the values
def Reset():
    f_name.set("")
    m_name.set("")
    l_name.set("")
    gender.set("")
    age.set("")
    home_address.set("")
    phone_number.set("")

Explanation:

In this code, the reset function is used for clearing the value you put in the text entry of adding new contacts.

Code for database and table creation

# For creating the database and the table
def Database():
    connectn = sqlite3.connect("contactdata.db")
    cursor = connectn.cursor()
    cursor.execute("CREATE TABLE IF NOT EXISTS `contactinformation` (id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, first_name TEXT, middle_name TEXT, last_name TEXT, gender TEXT, age TEXT, home_address TEXT, phone_number TEXT)")
    cursor.execute("SELECT * FROM `contactinformation` ORDER BY `last_name` ASC")
    fetchinfo = cursor.fetchall()
    for data in fetchinfo:
        tree.insert('', 'end', values=(data))
    cursor.close()
    connectn.close()

Explanation:

In this above code, we are defining the function database where we are creating the “connectn” object to connect the database “contactdata.db” of sqlite. The cursor object is used for the functioning of the SQLite functions .i.e cursor.execute() function will create the table “contactinformation “ if it doesn’t exist and cursor.fetchall() function fetches all the data into the variable fetch and later insert it into the tree.

Code for inserting contacts in the system

Insert Query for inserting into the database

#Insert query for inserting the value in database Table
def Submit():
    if f_name.get() == "" or m_name.get() == "" or l_name.get() == "" or gender.get() == "" or age.get() == "" or home_address.get() == "" or phone_number.get() == "":
        msgg = tkMessageBox.showwarning('', 'Please Complete All the Fields', icon="warning")
    else:
        tree.delete(*tree.get_children())
    connectn = sqlite3.connect("contactdata.db")
    cursor = connectn.cursor()

    cursor.execute("INSERT INTO `contactinformation` (first_name, middle_name, last_name, gender, age, home_address, phone_number ) VALUES(?, ?, ?, ?, ?, ?, ?)", (str(f_name.get()), str(m_name.get()), str(l_name.get()), str(gender.get()), int(age.get()), str(home_address.get()),
    int(phone_number.get())))

    connectn.commit()
    cursor.execute("SELECT * FROM `contactinformation` ORDER BY `last_name` ASC")
    fetchinfo = cursor.fetchall()

    for data in fetchinfo:
        tree.insert('', 'end', values=(data))
    cursor.close()
    connectn.close()
    f_name.set("")
    m_name.set("")
    l_name.set("")
    gender.set("")
    age.set("")
    home_address.set("")
    phone_number.set("")

Explanation:

The function def submit(): is used for actually inserting the values in the fields. This method demonstrates how to execute INSERT Query from python to add a new row into the SQLite table. In the first steps, it will check if any of the fields are empty and if the value is not filled in the text field it displays a message as” Please Complete All the Fields”. Otherwise once all the text fields are filled it executes the INSERT query and put the details into the database.

Module for frame, labels, text entry, and button for adding new contact form window

#For creating the frame, labels, text entry, and button for add new contact form window
def MyNewContact():
    global opennewwindow
    f_name.set("")
    m_name.set("")
    l_name.set("")
    gender.set("")

Code for updating the contacts in the system

Update Query for updating the database

#Update Query for updating the table in the database
def Update():
    if gender.get() == "":
        msgg = tkMessageBox.showwarning('', 'Please Complete The Required Field', icon="warning")
    else:
        tree.delete(*tree.get_children())
    connectn = sqlite3.connect("contactdata.db")
    cursor = connectn.cursor()
    cursor.execute("UPDATE `contactinformation` SET `first_name` = ?, `middle_name` = ? , `last_name` = ?, `gender` =?, `age` = ?, `home_address` = ?, `phone_number` = ? WHERE `id` = ?",
    (str(f_name.get()), str(m_name.get()), str(l_name.get()), str(gender.get()), int(age.get()), str(home_address.get()),
    str(phone_number.get()), int(id)))
    connectn.commit()
    cursor.execute("SELECT * FROM `contactinformation` ORDER BY `last_name` ASC")
    fetchinfo = cursor.fetchall()
    for data in fetchinfo:
        tree.insert('', 'end', values=(data))
    gender1 = gender.get()
    if not gender1:
        tkMessageBox.showerror("Please select the gender")

    cursor.close()
    connectn.close()

    f_name.set("")
    m_name.set("")
    l_name.set("")
    gender.set("")
    age.set("")
    home_address.set("")
    phone_number.set("")

Explanation:

Here we are providing the UPDATE query which allows us to UPDATE the row that is already present in the database. It will generate an error message as” ‘Please Complete The Required Field” specifically for gender if one of the fields is left to be filled.

For updating the row in the database you have to double-click the row which you want to update and perform the further operation.

Module to update contact form window

#Module for the update contact form window
def UpdateContact(event):
    global id, UpdateWindow
    curItem = tree.focus()
    contents = (tree.item(curItem))
    item = contents['values']
    id = item[0]
    f_name.set("")
    m_name.set("")
    l_name.set("")
    gender.set("")
    age.set("")
    home_address.set("")
    phone_number.set("")


    f_name.set(item[1])
    m_name.set(item[2])
    l_name.set(item[3])

    age.set(item[5])
    home_address.set(item[6])
    phone_number.set(item[7])


    UpdateWindow = Toplevel()
    UpdateWindow.title("Contact Information")
    UpdateWindow.geometry("500x520+0+0")
    UpdateWindow.resizable(0, 0)
    if 'Opennewwindow' in globals():
        Opennewwindow.destroy()

The code after execution gives the following result:

Output

Delete query for deleting the database

#Delete query for deleting the value
def Delete():
    if not tree.selection():
        msgg = tkMessageBox.showwarning('', 'Please Select the data!', icon="warning")
    else:
        msgg = tkMessageBox.askquestion('', 'Are You Sure You Want To Delete', icon="warning")
    if msgg == 'yes':
        curItem = tree.focus()
        contents = (tree.item(curItem))
        item = contents['values']
        tree.delete(curItem)
    connectn = sqlite3.connect("contactdata.db")
    cursor = connectn.cursor()
    cursor.execute("DELETE FROM `contactinformation` WHERE `id` = %d" % item[0])
    connectn.commit()
    cursor.close()
    connectn.close()

Explanation:

In this code, the user is asked about some action to which, the user answers yes or no. If yes it will delete the contact record in the table and if not it will remain the contact record in the table.

Output

Code for creating a table in the contact management system window

#creating a tables in contact management system
scrollbarx = Scrollbar(TableMargin, orient=HORIZONTAL)
scrollbary = Scrollbar(TableMargin, orient=VERTICAL)
tree = ttk.Treeview(TableMargin, columns=("Id", "First Name", "Middle Name", "Last Name", "Gender", "Age", "Home Address", "Phone Number"),
height=400, selectmode="extended", yscrollcommand=scrollbary.set, xscrollcommand=scrollbarx.set)
scrollbary.config(command=tree.yview)
scrollbary.pack(side=RIGHT, fill=Y)
scrollbarx.config(command=tree.xview)
scrollbarx.pack(side=BOTTOM, fill=X)

tree.heading('Id', text="Id", anchor=W)
tree.heading('First Name', text="First Name" ,anchor=W)
tree.heading('Middle Name', text="Middle Name", anchor=W)
tree.heading('Last Name', text="Last Name", anchor=W)
tree.heading('Gender', text="Gender", anchor=W)
tree.heading('Age', text="Age", anchor=W)
tree.heading('Home Address', text="Home Address", anchor=W)
tree.heading('Phone Number', text="phone Number", anchor=W)

tree.column('#0', stretch=NO, minwidth=0, width=0)
tree.column('#1', stretch=NO, minwidth=0, width=0)
tree.column('#2', stretch=NO, minwidth=0, width=80)
tree.column('#3', stretch=NO, minwidth=0, width=120)
tree.column('#4', stretch=NO, minwidth=0, width=90)
tree.column('#5', stretch=NO, minwidth=0, width=80)
tree.column('#6', stretch=NO, minwidth=0, width=30)
tree.column('#7', stretch=NO, minwidth=0, width=120)

tree.pack()
tree.bind('<Double-Button-1>', UpdateContact)

Here we can see that we have created a table for inserting the values First name, Middle name, Last name, Gender, Age, Address, Phone Number of the user for that we have made use of scrollbarx and scrollbary for scrolling horizontally and vertically.tree.pack() is used to organize the widgets in boxes or blocks.
