First Tkinter Program (Calculator)

 

How I created my first CALCULATOR using python programming!!! (Extremely Basic)

Basically, I used a module of python package that is Tkinter. Tkinter is basically a module in python used to create GUIs (Graphical User Interface). Through this module , you can create small apps , your own notepad , small games like tic tac toe, etc. You can download Python latest version from the link given below .

LINK - https://www.python.org/downloads/

I use visual studio code editor for editing my code. Most programmers use this editor . You can download it from https://code.visualstudio.com/download . 

After the installation of python , you can install the tkinter module using the following command - pip install tkinter , After the installation , You are good to go .

You can read tkinter python documentation from https://docs.python.org/3/library/tk.html and then you are good to go . I will provide the source code of my calculator . It is extremely basic.

source code : 

from tkinter import *

import time

root = Tk()

root.geometry('600x400')

root.title('First Program')

x = IntVar()

y = IntVar()

entry_1 = Entry(root,textvariable=x)

entry_2 = Entry(root,textvariable=y)

entry_1.pack()

entry_2.pack()

def add():

    name = int(entry_1.get())+int(entry_2.get())

    sent = f'{entry_1.get()} + {entry_2.get()} = {name}'

    print(sent)

    bc = Label(text=sent,bg='black',fg='white')

    bc.pack()

def sub():

    name = int(entry_1.get())-int(entry_2.get())

    sent = f'{entry_1.get()} - {entry_2.get()} = {name}'

    print(sent)

    bc = Label(text=sent,bg='black',fg='white')

    bc.pack()

def mult():

    name = int(entry_1.get())*int(entry_2.get())

    sent = f'{entry_1.get()} x {entry_2.get()} = {name}'

    print(sent)

    bc = Label(text=sent,bg='black',fg='white')

    bc.pack()

def div():

    name = int(entry_1.get())/int(entry_2.get())

    sent = f'{entry_1.get()} / {entry_2.get()} = {name}'

    print(sent)

    bc = Label(text=sent,bg='black',fg='white')

    bc.pack()

def back():

    txt = 'Thank you for using the calculator'

    bt = Label(text=txt,bg='black',fg='white')

    bt.pack()

    print(txt)

    root_2 = Tk()

    root_2.geometry('200x100')

    xy = Label(root_2,text='Are you sure you want to quit ? ',bg='black',fg='white')

    xy.pack()

    xyz = Button(root_2,text='Quit',bg='black',fg='white',command=root.quit)

    xyz.pack()

    root_2.quit()

    root_2.mainloop()

addition = Button(text='+',bg='white',fg='black',command=add)

subtraction = Button(text='-',bg='white',fg='black',command=sub)

multiply = Button(text='x',bg='white',fg='black',command=mult)

divide = Button(text='/',bg='white',fg='black',command=div)

Q = Button(text='Quit',bg='white',fg='black',command=back)

addition.pack()

subtraction.pack()

multiply.pack()

divide.pack()   

Q.pack()

root.mainloop()

You can copy this source code if you want!!!...If you have reached till here . Thank you so much for reading this blog. Have a nice day!!!
