Python Program Calculate Sum of n Numbers

Python program to find sum of n numbers; Through this tutorial, i am going to show you how to calculate or find sum of n numbers in python.

In this tutorial, i will write python programs to find or calculate sum of n numbers, sum of n even number and sum of n odd number using for loop, while loop and function.

Python Program Calculate Sum of n Numbers

See the following python programs to find or calculate sum of n numbers, sum of n even number and sum of n odd number using for loop, while loop and function:

Python program to find sum of n numbers using for loop
Python program to find sum of n numbers using while loop
Python program to find sum of all numbers in list
Python program to find sum of n odd numbers
Python program to find sum of n even numbers

Python program to find sum of n numbers using for loop

Let’s see the following program to find sum of n numbers using for loop in python; as shown below:

n = input("Enter Number to calculate sum")
n = int (n)
sum = 0
for num in range(0, n+1, 1):
    sum = sum+num
print("SUM of first ", n, "numbers is: ", sum )

Output:

Enter Number to calculate sum 5 
Sum of first 5 number is: 15

Python program to find sum of n numbers using while loop

See the following program to find sum of n numbers using while loop in python; as shown below:

n = input("Enter Number to calculate sum")
n = int (n)
total_numbers = n
sum=0
while (n >= 0):
    sum += n
    n-=1
print ("sum using while loop ", sum)

Output:

Enter Number to calculate sum 5 
Sum using while loop  15

Python program to find sum of all numbers in list

Let’s see the following program to find sum of all numbers from list in python; as shown below:

sum = 0
list = [11,4,5,7,99,10,12]
for num in list:
    sum = sum +num
print ("sum of list element is : ", sum)

Output:

sum of list element is :  148

Python program to find sum of n odd numbers

n = input("Enter Number to calculate sum")
n = int (n)
sum = 0
for num in range(0, n+1, 1):
    
    if(not (num % 2) == 0):
      sum += num;
      
print("SUM of odd numbers is: ", sum )

Output:

Enter Number to calculate sum 5 
SUM of odd numbers is:  9

Python program to find sum of n even numbers

n = input("Enter Number to calculate sum")
n = int (n)
sum = 0
for num in range(0, n+1, 1):
    
    if((num % 2) == 0):
      sum += num;
      
print("SUM of even numbers is: ", sum )

Output:

Enter Number to calculate sum 5 
SUM of even numbers is:  9
