Sum of Two Numbers In Python or Adding Two Numbers

This article is an easy way to Print the Sum of Two Numbers In Python. This code will dynamically sum the 2 given numbers when the user clicks on the calculate button.

How To Print Sum Of Two Numbers using Python: Project Information

The code uses the Tkinter module to create a layout and widgets that may call specific Python functions.

About The Project

We will be the usage of Python programming language because it’s widely used as an advanced-degree programming language for a general approach to the developer. This tutorial also includes the downloadable Sum of 2 Numbers In Python source code.

To start creating How To Print Sum Of Two Numbers, make sure that you have Pycharm IDE installed on your computer.

How To Add or Sum of Two Numbers In Python With Source Code

Python Program To Add Two Numbers Code Explanations

1. Import Tkinter

The code given below is for importing tkinter modules.

from tkinter import *
from tkinter import messagebox

Importing the tkinter modules.

2. GUI Design

The code given below is for the GUI design.

        def check():



                    self.label1 = Label(self, text="Enter Number 1" ,  fg = 'black', font=("courier-new", 18, 'bold'))
                    self.label1.place(x=280, y=180)
                    self.num1 = Entry(self, textvariable=self.a,bg='light blue', width=45)
                    self.num1.place(x=480, y=190)
                    self.label2 = Label(self, text="Enter Number 2" , fg = 'black', font=("courier-new", 18, 'bold'))
                    self.label2.place(x=280, y=250)
                    self.num2 = Entry(self, textvariable=self.b,bg='light blue', width=45)
                    self.num2.place(x=480, y=255)
                    self.butt = Button(self, text="Calculate",bg ='green', font=10, width=8, command=chex).place(x=580, y=300)
                    self.label3 = Label(self, text="Sum of Two Numbers", fg='black', font=("courier-new", 24, 'bold'))
                    self.label3.place(x=380, y=30)

This module which is the design of this project uses Graphical User Interface (GUI).

Output:

3. Calculate Two Numbers

The code given below is for calculating the two numbers.

        def chex():
            if not self.num1.get() and not self.num2.get():
                print("Please enter a number")
            else:
                res = int(self.num1.get()) + int(self.num2.get())
                messagebox.showinfo('Sum of Two Numbers', "The answer is: %d" % (res))
                self.num1.set = ""
                self.num2.set = ""

This module calculates the two input numbers in addition.

Output:
