Python is one of the most popular programming languages used today. This Python guide will help you navigate through many challenges you’ll face in using it.
The built-in functionabs()will return the absolute value of a number that you pass to it. In mathematics,absolute valuerefers to the distance that a number is on the number line from 0. Absolute value does not take into consideration which direction from zero the number lies, meaning that ...
A function in Python performs a task and returns a result. In this chapter, we will start with the basics of functions. Then we look at using the built-in functions. These are the core functions that are always available, meaning they don't require an explicit import into your namespace...

Chaining function invocations The built-in template functions we have been using operate pretty much as regular functions we use when writing our code. As such, we can actually chain their invocation, meaning that, for example, we can sort an array and then pass the result to the join functi...
Bytearray objects are created with the built-in function bytearray(). Buffer objects are not directly supported by Python syntax, but can be createdby calling the built-in function buffer(). They don’t supportconcatenation or repetition. ...
