# Python Program to Add Two Numbers

In this Python Program to add two numbers, you’ll learn how to add two given numbers given by the user.

To properly understand how to add two given numbers, you should have the knowledge of following Python programming topics:

1.Python Input, Output, and Import

2.Python Variables and Data Types

In the following program, we have used the arithmetic addition operator i.e (+) to adds two numbers.

## Python Program to Add Two Numbers

#Python Program to Add two numbers # This program adds two numbers n1 = 2.5 n2 = 4.3 # Add two numbers sum = float(n1) + float(n2) # Display the sum print('The sum of {0} and {1} is {2}'.format(n1, n2, sum))

**Output**

The sum of 2.5 and 4.3 is 6.8

As mentioned above Python uses all the mathematics operation so by Changing **(+)** operator, we can subtract **(-)**, multiply **(*)**, divide **(/)**, floor divide **(//)** or find the remainder (%) of two numbers.

## Python Program to Add Two Numbers Given By User

# Store input numbers num1 = input('Enter first number: ') num2 = input('Enter second number: ') # Add two numbers sum = float(num1) + float(num2) # Display the sum print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

**Output:**

Enter first number: 3 Enter second number: 4 The sum of 3 and 4 is 7

In the above program, we asked the user to enter two numbers and this program displays the sum of two numbers entered by the user.

We use the built-in function input() to take the input. input() returns a string, so we convert it into the number using the float() function.

An alternative to this, we can perform this addition in a single statement without using any variables as follows.

print('The sum is %.1f' %(float(input('Enter first number: '))+float(input('Enter second number: '))))

Although this program uses no variable (memory efficient), it is not quite readable. Some people will have difficulty understanding it. It is better to write clear codes.

So, there is always a compromise between clarity and efficiency. We need to strike a balance.
