## Python Program to Find Sum and Average of n Numbers

- Write a Program Find/Calculate the Average of n natural numbers using loop in Python
- Python Program Find Sum and Average of n natural numbers in python using while loop
- Python Program to Calculate Sum and Average of N Numbers Using Math formula

### Write a Program Calculate Sum & Average of n natural numbers using For loop in Python

n = input("Enter Number to calculate sum & average") n = int (n) sum = 0 for num in range(0, n+1, 1): sum = sum+num average = sum / n print("SUM of", n, "numbers is: ", sum ) print("Average of", n, "natural number is: ", average)

**Output**:

Enter Number to calculate sum & average 5 SUM of 5 numbers is: 15 Average of 5 natural number is: 3.0

### Python Program Find Sum and Average of n natural numbers in python using while loop

n = input("Enter Number to calculate sum and average") n = int (n) totalNo = n sum=0 while (n >= 0): sum += n n-=1 average = sum / totalNo print ("sum of ", totalNo ,"using while loop ", sum) print ("average of", totalNo ,"using while loop ", average)

**Output**:

Enter Number to calculate sum and average 5 sum of 5 using while loop 15 average of 5 using while loop 3.0

### Python Program to Calculate Sum and Average of N Numbers Using Math formula

n = input("Enter a number to calculate average and sum") n = int (n) sum = n * (n+1) / 2 average = ( n * (n+1) / 2) / n print("Sum of the first ", n, "natural numbers using formula is: ", sum ) print("Average of the first ", n, "natural numbers using formula is: ", average )

**Output**:

Enter a number to calculate average and sum 5 Sum of the first 5 natural numbers using formula is: 15.0 Average of the first 5 natural numbers using formula is: 3.0
