Python sum() function

“

- The built-in function sum is a powerful computational tool, when working with numerical data in Python. The function sum is best suited to take in a sequence of integers as input. And it returns the sum of the items in the given sequence. To illustrate how this function can be used, I'll be walking through a couple of examples. First, let's say that I have a variable named nums, that contains a tuple of integers. To compute the sum of the items in nums, I can call the function sum and pass in nums. It will look like this. Now, go ahead and run this cell. There. I got 18 as a sum. Next, say that I have a variable named listN that contains a list of integers. To compute the sum of the items in listN, I can call the function sum and pass in listN. It would look like this. I'll go ahead and run this cell. There it is. I got negative 21 as the sum. Now that you've seen how to use the function sum, this tool is at…
