Adding several numbers together is a common intermediate step in many computations, so sum() is a pretty handy tool for a Python programmer. Python’s built-in function sum() is an efficient and Pythonic way to sum a list of numeric values.
This is a portion of the complete course, which you can find here:

The rest of the course covers how to:
- Concatenate lists and tuples with sum()
- Use sum() to approach common summation problems
- Use appropriate values for the arguments in sum()
- Decide between sum() and alternative tools to sum and concatenate objects
