In this post, we will learn how to find the average of two numbers using the Python Programming language.
Average is defined as a found by adding all the numbers in a set together and then dividing them by the quantity of numbers in the list.
- Average = Total sum / Total no. of terms
We will use the following approaches to find the average of two numbers:
- Using Standard Method
- Using User-Input
- Using Function
So, without further ado, let’s begin this tutorial.
Python Program to Find Average of Two Numbers
# Python Program to Find Average of Two Numbers
# First Number
a = 5
# Second Number
b = 10
# Calculating average of two numbers
avg = (a + b) / 2
# Display output
print("Average of two numbers = %.2f" %avg)
Output
Average of two numbers = 7.50
Python Program to Find Average of Two Numbers With User Input
# Python Program to Find Average of Two Numbers With User Input
# Asking for input
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
# Calculating average of two numbers
avg = (num1 + num2) / 2
# Display output
print("Average of two numbers = %.1f" %avg)
Output
Enter the first number: 18
Enter the second number: 24
Average of two numbers = 21.0
How Does This Program Work?
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
The user is asked to enter two integers. Here, input is taken with the help of the input() function. The float() function is used to convert the input to a floating data type.
# Calculating average of two numbers avg = (num1 + num2) / 2
Then, we find the average of two numbers using the average formula: Average = Total sum / Total no. of terms.
# Display output
print("Average of two numbers = %.1f" %avg)
The average of two numbers is displayed on the screen using the print() function. We have used %.1f format specifier to limit the value of average to 1 decimal place.
Python Program to Find Average of Two Numbers Using Function
# Python Program to Find Average of Two Numbers Using Function
def average(a, b):
return (a + b)/2
# Asking for input
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))
# Calling out custom function
avg = average(num1, num2)
# Display output
print("Average of two numbers = %.2f" %avg)
Output
Enter the first number: 7
Enter the second number: 8
Average of two numbers = 7.50
