In this article, we will discuss different ways to get the sum of all numbers in a list in Python.
Table Of Contents
Method 1: Using sum() function
Python provides a function sum(). It accepts a sequence as argument, and returns the sum of all elements in the given sequence. We can pass a list of numbers to it as an argument, and it will return the sum of all numbers in that list. Let’s see an example,
listOfNums = [11, 12, 13, 14, 15, 16, 17, 18, 19, 20] # get sum of all numbers in the list total = sum(listOfNums) print(total)
Output :
155
We got the sum of all numbers in the list.
Method 2: Using for loop
Iterate over all the numbers in a list, and add them one by one. Let’s see an example,
listOfNums = [11, 12, 13, 14, 15, 16, 17, 18, 19, 20] total = 0 # get sum of all numbers in the list for elem in listOfNums: total = total + elem print(total)
Output :
155
We got the sum of all numbers in the list.
Method 3: Using Generator expression
Iterate over all the numbers in a list using Generator expression. For each element, convert that to int, and pass them to sum() function. It will return the total of all number in the list. Let’s see an example,
listOfNums = ['11', '12', 13, '14', 15, '16', 17, 18, 19, 20] # get sum of all numbers in the list total = sum(int(elem) for elem in listOfNums) print(total)
Output :
155
We got the sum of all numbers in the list.
Summary
We learned how to get the sum of all numbers in a list. Thanks.
