Task :
To find the sum of all the elements in a list.
Approach :
- Read the input number asking for the length of the list using
input()orraw_input(). - Initialize an empty list
lst = []. - Read each number using a
for loop. - In the for loop append each number to the list.
- Now we use a predefined function
sum()to find the sum of all the elements in a list. - Print the result.
Program :
lst = []num = int(input('How many numbers: '))for n in range(num): numbers = int(input('Enter number ')) lst.append(numbers)print("Sum of elements in given list is :", sum(lst))Output :
That’s how we can calculate the sum of elements in a list.
