The Most Numbers

We have prepared a set of Editor's Choice Solutions. You will see them first after you solve the mission. In order to see all other solutions you should change the filter.

Let's work with numbers!

You are given an array of numbers (floats). You should find the difference between the maximum and minimum element. Your function should be able to handle an undefined amount of arguments. For an empty argument list, the function should return 0.

Floating-point numbers are represented in computer hardware as base 2 (binary) fractions. So we should check the result with ±0.001 precision.
Think about how to work with an arbitrary number of arguments.

Input: An arbitrary number of arguments as numbers (int, float).

Output: The difference between maximum and minimum as a number (int, float).


checkio(1, 2, 3) == 2
checkio(5, -5) == 10
checkio(10.2, -2.2, 0, 1.1, 0.5) == 12.4
checkio() == 0

How it is used: Here you will learn about passing an undefined amount of arguments to functions.

Precondition: 0 ≤ len(args) ≤ 20
all(-100 < x < 100 for x in args)
all(isinstance(x, (int, float)) for x in args)

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=py config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.

Pair Programming (Beta-version)

Welcome to Pair Programming! Engage in real-time collaboration on coding projects by starting a session and sharing the provided unique URL with friends or colleagues. This feature is perfect for joint project development, debugging, or learning new skills together. Simply click 'Start Session' to begin your collaborative coding journey!
