The modern world is filled with means of communication - the social networks, messengers, phone calls, SMS etc. But sometimes in every communication channel a flaw can be detected and in the moments like that you think to yourself: "I should create my own messenger which won’t have problems like this one".
In this mission you’ll get your chance.
Your task is to create a Chat class which could help a Human(name) and Robot(serial_number) to make a conversation. This class should have a few methods:
connect_human() - connects human to the chat.
connect_robot() - connects robot to the chat.
show_human_dialogue() - shows the dialog as the human sees it - as simple text.
show_robot_dialogue() - shows the dialog as the robot perceives it - as the set of ones and zeroes. To simplify the task, just replace every vowel ('aeiouAEIOU') with "0", and the rest symbols (consonants, white spaces and special signs like ",", "!", etc.) with "1".
Dialog for the human should be displayed like this:
(human name) said: message text
(robot serial number): message text
For the robot:
(human name) said: 11100100011
(robot serial number) said: 100011100101
Interlocutors should have a send() method for sending messages to the dialog.
In this mission you could use the Mediator design pattern.


chat = Chat()
karl = Human("Karl")
bot = Robot("R2D2")
karl.send("Hi! What's new?")
bot.send("Hello, human. Could we speak later about it?")
chat.show_human_dialogue() == """Karl said: Hi! What's new?
R2D2 said: Hello, human. Could we speak later about it?"""
chat.show_robot_dialogue() == """Karl said: 101111011111011
R2D2 said: 10110111010111100111101110011101011010011011"""

Input: Interlocutors and the text of messages.

Output: A dialog (the multiline string).

How it is used: For creating a connection and sending/receiving the information.

Precondition: 2 interlocutors.

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.

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!
