Introduction
Calculating the average of N numbers is a simple task that involves taking the sum of the numbers and dividing it by the total number of numbers. In Python, we can use loops and conditional statements to read N numbers from users and calculate their average.
Prerequisites
Before we start writing the program, we need to have a basic understanding of Python programming language. We also need to know how to use loops and conditional statements in Python.

Steps to Calculate the Average of N Numbers in Python
- Here are the steps to calculate the average of N numbers in Python:
- First, we need to ask the user to enter the total number of numbers they want to calculate the average for. We can use the input() function to get the user input.
- Next, we need to use a loop to read N numbers from the user. We can use a for loop or a while loop to achieve this.
- After reading the N numbers, we need to calculate their sum. We can use a variable to keep track of the sum of the numbers.
- Once we have the sum of the numbers, we can calculate the average by dividing the sum by the total number of numbers.
- Finally, we can print the average of the N numbers to the user.

Example Program
- Here is an example program that reads N numbers from the user and calculates their average:
# Python program to calculate the average of N numbers
# Step 1: Ask the user to enter the total number of numbers
n = int(input("Enter the total number of numbers: "))
# Step 2: Use a loop to read N numbers from the user
sum = 0
for i in range(n):
num = int(input("Enter a number: "))
sum += num
# Step 3: Calculate the average of the N numbers
average = sum / n
# Step 4: Print the average to the user
print("The average of the", n, "numbers is", average)
Output:
Enter the total number of numbers: 5
Enter a number: 5
Enter a number: 5
Enter a number: 5
Enter a number: 5
Enter a number: 5
The average of the 5 numbers is 5.0
Calculating the average of N numbers is a simple task that can be achieved using loops and conditional statements in Python. In this blog post, we discussed how to write a Python program to read N numbers from users and calculate their average. We hope this blog post was helpful to you.

FAQ : Calculate the Average of N Numbers Using Python
What is the meaning of "n" in this program?
In this program, "n" refers to the total number of numbers that the user wants to enter to calculate the average.
What is the formula to calculate the average of n numbers?
The formula to calculate the average of n numbers is to add all the numbers and divide the sum by the total number of numbers. Mathematically, it can be represented as:
Average = (Sum of numbers) / (Total number of numbers)
What is the easiest way to calculate the average of n numbers in Python?
The easiest way to calculate the average of n numbers in Python is by using a for loop. First, we define the total number of inputs we want to enter. Then, we take the numbers and calculate the total sum of those numbers using the for loop. Finally, we calculate the average of those numbers using a formula and print the average value.
Can we use a while loop to calculate the average of n numbers in Python?
Yes, we can use a while loop to calculate the average of n numbers in Python. We can use a while loop to read n numbers from the user and calculate their sum. Once we have the sum of the numbers, we can calculate the average by dividing the sum by the total number of numbers.
Is there any built-in function in Python to calculate the average of n numbers?
Yes, there is a built-in function in Python to calculate the average of n numbers. We can use the mean() method of the statistics module to directly calculate the average of the elements of the list. We will pass the given list of numbers as input to the mean() method and it will return the average of numbers.
