# Python program to calculate the sum of elements in a list

Hello everyone, am back to discuss about a new python program. Here we learn how to sum all the elements in a list quite easily. We use a predefined function called sum() and apply it to the list, the functions returns the sum of all the elements in a list.

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 :
