Python programming to add two numbers

Learn how to add two number in python language in details:

 

In this article, you’ll learn how to add two number in python language without input from keyboard or input from the keyboard in details with explanation and example:

If you learn the earlier language like C, C++ then you easily observe that programming in python language is easier than another language that’s why many software developers choose python language to establish software. To learn more

Explanation:

  • First, create two variables to store two number and initialize the value like num1=45 and num2=32 then
  • Create the third variable to store the sum of two number
  • int is a predefined data type, it means the given value is an integer and we also use float data types for real number.
  • The print is a built-in function to display the result on the screen.

Example1: Write a program in python to add two number

Solution:

#python program to add two number

num1 = 45

num2 = 32

sum = int(num1) + int(num2)

print(‘The sum of {0} and {1} is {2}’.format(num1,num2,sum))

 

The out of this program:

The sum of 45 and 32 is 77

Note: # is used as a comment which is ignored by the interpreted.

Example2: Write a program in python to add two number

Solution:

#python program to add two number

num1 = 55.23

num2 = 54.67

sum = float(num1) + float(num2)

print(‘The sum of {0} and {1} is {2}’.format(num1,num2,sum))

 

The out of this program:

The sum of 55.23 and 54.67 is 109.9

 

Example3: Write a program in python to add two number, input is given by user from the keyboard

Solution:

#python program to add two number

num1 = input(‘Enter first number: ‘)

num2 = input(‘Enter second number: ‘)

sum = int(num1) + int(num2)

print(‘The sum of {0} and {1} is {2}’.format(num1,num2,sum))

 

The output of this program:

Enter first number: 78

Enter second number: 54

The sum of 78 and 54 is 132

Note: input() is a build-in function, it use to take input from the user.

Example4: Write a program in python to add two number, input is given by user from the keyboard

Solution:

#python program to add two number

num1 = input(‘Enter first number: ‘)

num2 = input(‘Enter second number: ‘)

sum = float(num1) + float(num2)

print(‘The sum of {0} and {1} is {2}’.format(num1,num2,sum))

 

The output of this program:

Enter first number: 78

Enter second number: 54

The sum of 58.32 and 45.65 is 103.97
