The Best Number Ever

The Best Number Ever

English FR RU UK

It was Sheldon's version and his best number. But you have the coding skills to prove that there is a better number, or prove Sheldon sheldon right. You can return any number, but use the code to prove your number is the best!

This mission is pretty simple to solve. You are given a function called "checkio" which will return any number (integer or float).

Let's write an essay in python code which will explain why is your number is the best. Publishing the default solution will only earn you 0 points as the goal is to earn points through votes for your code essay.

Input: Nothing.

Output: A number as an integer or a float or a complex.


isinstance(checkio(), (int, float, complex))

How it is used: This mission revolves around code and math literacy.

Invalid hot key. Each hot key should be unique and valid

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.
