Question

write a programme in python to input a list cantaing a number and calculate the sum of all ODD element present inside the list? if list is (1,2,3,4,5,6,7) then sum =1+3+5+7+=16​

Answer 1

Answer:

sum=0;

number=(1,2,3,4,5,6,7);

for i in number:

if (i%2)==1:

sum=sum+i;

print (sum);

Answer 2

Answer:

n=int(input("enter the max no of elements you want to enter"))

lis1=[0]*n

even=0

odd=0

for i in range(n):

   lis1[i]=int(input("Enter the elements"))

print("Elements in the list are",lis1)

for i in range(n):

   if (lis1[i]%2==0):

       even=even+lis1[i]

   else:

       odd=odd+lis1[i]

print("Sum of even elements are",even)

print("Sum of odd elements are",odd)

Output:

enter the max no of elements you want to enter10

Enter the elements12

Enter the elements15

Enter the elements14

Enter the elements19

Enter the elements16

Enter the elements18

Enter the elements17

Enter the elements1

Enter the elements2

Enter the elements3

Elements in the list are [12, 15, 14, 19, 16, 18, 17, 1, 2, 3]

Sum of even elements are 62

Sum of odd elements are 55

Explanation:

1. n variable is created to store length of the list

2. A list is created with same length

3. Using for loop elements are taken from the user and inserted in the list.

4. Using print statement elements are displayed.

5. condition statements are used to differentiate odd and even numbers.

6. modulus operator returns reminder

7. If the element returns 0 when divided by 2 we can confirm it as even number else odd.

8. Inside for loop even numbers and odd numbers are added to the variables even and odd.

9. Display the sum of even and odd numbers using print statement
