Python Built-in Functions

This tutorial will go through a few of the built-in functions that can be used with numeric data types in Python 3. Becoming familiar with these methods can give you more flexibility when programming. We’ll go over the following functions: abs() for absolute value, divmod() to find a quotient and remainder simultaneously, pow() to raise a number to a certain power, round() to round a number to a certain decimal point, sum() to calculate the sum of the items in an iterable data type.

A function is a block of instructions that, once defined, both performs an action once the function is called and makes that action available for later use. Functions make code more modular, allowing you to use the same code over and over again. In this tutorial, we’ll go over how to define your own functions to use in your coding projects.
