Python difference between two numbers | Example code

  • by

To find the positive difference between the two numbers we have subtracted the smaller number from the larger one in Python. Use an if statement to find which number is bigger.

Get the difference between two numbers in Python

Simple example code.

num1 = 100
num2 = 50

if num1 > num2:
    diff = num1 - num2
    diff = num2 - num1


Output: 50

Using abs() Function

The abs() method returns the absolute value of the given number. The difference is always positive.

num1 = 23
num2 = 45

diff = abs(num1 - num2)


Output: 22

Get the difference between user input numbers

Inputs are scanned using the input() function and stored in variables n1 and n2. Since input() returns a string, we convert the string to a number using the int() function.

n1 = int(input("Enter first number: "))
n2 = int(input("Enter second number: "))

if n1 > n2:
    diff = n1 - n2
    diff = n2 - n1

print("The difference is:",diff)
