Task :

To find the sum of all the elements in a list.

Approach :

  • Read input number asking for length of the list using input() or raw_input().
  • Initialise an empty list lst = .
  • Read each number using a for loop.
  • In the for loop append each number to the list.
  • Now we use 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 :
