Python program to calculate the sum of odd and even numbers in a list

In this tutorial, we will discuss the Python program to calculate the sum of odd and even numbers in a list

In this article, we are going to learn the concept of how to calculate the sum of odd and even numbers in the Python programming language

Python program: Calculate Addition of odd and even in a list using user input — Addition of odd and even

What is even or odd numbers?

When any integer value which ends in 0,2,4,6,8 is divided by two it is called as an even number

Example for even numbers – 34,-64,78,788

When any integer value which ends in 0,1,3,5,7,9 is not divided by two it is called as an odd number

Example for odd numbers – 33,-69,75,785

Here, we can use a modular operator to find odd or even number in the list

if n%2==0 n is an even number

if n%2==1 n is an odd number

Python program to Calculate Addition of odd and even

Calculating the sum of odd and even numbers using for loop

Program 1

In this program, the user prompts the program to add some numbers to the list, and then the program calculates the sum of odd and even numbers from the list using the “for loop.”

# Python code to Calculate sum of odd and even in a list using while loop
#input list
NumList=list(map(int, input("Enter numbers separated by spaces: ").split()))
#initialize sums
even_Sum=0
odd_Sum=0

#Loop through the list
for num in NumList:
    if num%2==0:
         even_Sum+=num  #Add to even sum
    else:
          odd_Sum+=num  #Add to odd sum
    
    #print the result
    
print(f"Sum of even numbers:{even_Sum}")
print(f"Sum of even numbers:{odd_Sum}")

When the above code is executed, it produces the following results

Enter numbers separated by spaces: 5 6 7 8 9 10 11 12 13 14
Sum of even numbers:50
Sum of even numbers:45

Method

To begin with, define a list without including the elements named NumList=[].
The program prompts to add some numbers to the list from the user
Next, declare and initialize two variables: odd_Sum=0, even_Sum=0
Then, using the “for loop”, elements are picked individually from the list to determine odd and even numbers
Next, “if statements” are used to find a number, and then, if it is even, it is added to the variable evenSum.If the number is not even, it is dealt with by an “else statement”.
After that, the “else statement” adds the element to the variable oddSum.
Finally, the sums of odd numbers and even numbers are displayed.

Calculating the sum of odd and even numbers using “while loop”

In this program, the user prompts the program to add some numbers to the list, and then the program calculates the sum of odd and even numbers from the list using the “=while loop.”

Program 2

# Python code to Calculate sum of odd and even in a list using while loop
#input list
num=list(map(int, input("Enter numbers separated by spaces: ").split()))
#initialized variable
even_Sum=0
odd_Sum=0
index=0

#Loop through the list using while
while index<len(num):
    if num[index]%2==0:
        even_Sum+=num[index]
    
    else:
        odd_Sum+=num[index]

    index+=1
        
print(f"Sum of even numbers: {even_Sum}")
print(f"Sum of odd numbers: {odd_Sum}")

When the above code is executed, it produces the following results

Enter numbers separated by spaces: 3 6 9 12 15 18 21 24 27 30
Sum of even numbers: 90
Sum of odd numbers: 75
