Hello everyone, I am back to discuss 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 function returns the sum of all the elements in a list. So lets calculate the sum of elements in a list.

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.
