Building Base

Building Base


The singularity has happened, and we are being made to build the ideal robo-city for our overlords. In this shining robotropolis, all buildings will be rectangular and all streets laid along south-north and east-west lines in a glorious grid. Before we get started, we have to create a class to represent the perfect building.

Because all the buildings in the city are rectangular and their walls are parallel to the streets, we can define any building using only the coordinates of South-Western corner, two arguments (the length of the west to east walls and the length of the north to south wall) along with the height of the building. These values are described as positive numbers using conventional units. The origin point of our coordinate system lies in the South-West , as a result, the northern corner ends up having the greater coordinate value than the southern corner. To complete this mission we need to use a couple of operations. See the class description below.

class Building(south, west, width_WE, width_NS, height=10)

Returns a new Building instance with the South-West corner at [south, west] coordinates, the size is width_WE by width_NS and the height of the building is height. "height" is a positive number with a default value of 10.

Building(10, 10, 1, 2, 2)
Building(10, 10, 1, 2, 2)
Building(0, 0, 10.5, 2.546)
Building(0, 0, 10.5, 2.546, 10)


Returns a dictionary with the coordinates of the building corners. The dictionary has following keys: "north-west", "north-east", "south-west", "south-east". The values are lists or tuples with two numbers.

Building(1, 2, 2, 2).corners()
{"north-west": [3, 2], "north-east": [3, 4], "south-west": [1, 2], "south-east": [1, 4]}


Returns the area of the building.

Building(1, 2.5, 4.2, 1.25).area()


Returns the volume of the building.

Building(1, 2.5, 4.2, 1.25, 101).volume()


This is a string representation of the Building. This method is used for "print" or "str" conversion. Returns the string in the following view:
"Building({south}, {west}, {width_we}, {width_ns}, {height})"

str(Building(0, 0, 10.5, 2.546))
"Building(0, 0, 10.5, 2.546, 10)"

In this mission, all data will be correct and you don't need to implement value checking.

Input: Statements and expression with the Building class.

Output: The behavior as described.

How it is used: Here you will learn how to write a simple class with minimal functionality to achieve greater glory for Robonia.

Precondition: All data are correct.

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

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.
