How to Calculate Sum of List in Python

In this article, you will learn how to calculate the sum of a list in Python.

Let’s say you have a list named ‘a’ with value [1, 2, 3, 4, 5].

a = [1, 2, 3, 4, 5]

In order to calculate the sum of a list, you can use the sum() method.

a = [1, 2, 3, 4, 5]

print(sum(a))
# => 15

Note: The sum() method functions by adding all items of an iterable and returning the result.
