🙋 Introduction

In the world of programming, dealing with numerical data and performing calculations is a fundamental skill. One common task is finding the average of a set of numbers. This is a basic operation used in various applications, ranging from statistical analysis to data processing.

In this tutorial, we will explore a Python program designed to find the average of N numbers. The program takes a user-specified number of inputs, calculates their sum, and then computes the average.

📄 Example

Let's delve into the Python code that accomplishes this task.

find_average.py

Copied

# Function to find the average of N numbers
def find_average(n):
    sum_of_numbers = 0

    # Input N numbers from the user
    print(f"Enter {n} numbers:")
    
    for i in range(n):
        # Input each number and add to the sum
        number = float(input())
        sum_of_numbers += number

    # Calculate the average
    average = sum_of_numbers / n
    return average

# Driver program
# Replace this value with your desired number of inputs (N)
n = 5

# Call the function to find the average
result = find_average(n)

# Display the result
print(f"The average of the entered numbers is: {result}")

💻 Testing the Program

To test the program with different numbers, modify the value of n in the code.

Output

Enter 5 numbers:
1 2 3 4 5 
The average of the entered numbers is: 3.000000

🧠 How the Program Works

The program defines a function find_average that takes an integer n as input, prompts the user to input n numbers, calculates their sum, and then computes and returns the average.
Replace the value of n in the main program with your desired number of inputs.
The program calls the find_average function, and the result is displayed.

🧐 Understanding the Concept to find Average of N Numbers

Before delving into the code, let's understand the concept behind finding the average of N numbers. The program uses a loop to input N numbers, calculates their sum, and then divides the sum by N to find the average.

For example, if the user enters 5 numbers (10, 15, 20, 25, 30), the program calculates (10 + 15 + 20 + 25 + 30) / 5, resulting in an average of 20.
