Python Program To Find Average Of n Numbers (2 Ways)

In this tutorial, you will learn to write a Python program to find average of n numbers.

The average of n numbers is the sum of those n numbers divided by n.

For example, the average of 1, 2, 3, 4, and 5 is (1+2+3+4+5)/5 = 3.

To understand this program you should have an understanding of the following topics:

1. While Loop
2. For Loop

1: Python Program To Find Average Of n Numbers Using While Loop

n = int(input("Enter the number of elements to be inserted: "))
sum = 0
i = 1

while i <= n:
    num = float(input("Enter element " + str(i) + ": "))
    sum += num
    i += 1

avg = sum / n
print("Average of", n, "numbers is: ", avg)

Output

In this program, we first take input from the user to determine the number of elements to be inserted.

We then use a while loop to take input for each element and add it to a running sum.

After all elements have been added, we calculate the average by dividing the sum by the number of elements and print the result.

2: Python Program To Find Average Of n Numbers Using For Loop

n = int(input("Enter the number of elements to be inserted: "))
sum = 0

for i in range(1, n+1):
    num = float(input("Enter element " + str(i) + ": "))
    sum += num

avg = sum / n
print("Average of", n, "numbers is: ", avg)

Output

In this program, we first take input from the user to determine the number of elements to be inserted.

We then use a for loop to take input for each element and add it to a running sum.

After all elements have been added, we calculate the average by dividing the sum by the number of elements and print the result.
