Command-line tool for playing CheckiO games.

CheckiO - Coding games for beginners and advanced programmers where you can improve your coding skills by solving engaging challenges.


python3 is required

$ pip3 install --upgrade checkio_client

or if you plan to contribute, you can create a clone in a specific folder and install from there

$ git clone
$ cd checkio-client
$ pip install -e .

After the installation a new checkio command becomes available.


your first command should be

$ checkio config

you'll need a key in order to finish it. You can obtain the API Key by following this link for Python, and this one for JavaScript.

You can find all of the available commands by using

$ checkio -h

and the detailed help for a specific command by using (for example, for a config command)

$ checkio config -h

The configuration process will create .checkio in your home folder along with the config.ini file in it

default_domain = py

key = b30523506050473b8f33ca440101026a


Run and Check your solution

Here is a simple way in which you can get your solution for Median mission

$ checkio init median checkio_solutions/

here you have two options to test your solution. The first one is by using the checkio command

$ checkio check median

and the second one is to simply execute the solution with --check argument (without it will simply run the solution)

$ checkio_solutions/ --check

after the successful check you will get a link for other players’ solutions and a link for sharing your own solution

Sync all your solutions on one folder

$ checkio sync ~/checkio_solutions

will save all of your solutions in folder ~/checkio_solutions. Check out help for command sync in order to learn more about the synchronization options

$ checkio sync -h

your last synchronized folder will be saved into ~/.checkio/config.ini, so if you’ll need to resync your solutions you can simply do

$ checkio sync

and to check and run the solutions by using the simpler command

$ checkio check median
$ checkio run median

Use multiple domains (py and js)

if you configure Python as a default service, you can still use JS. In order to do so you need to add a key in config file for the js_checkio section, and then you can run any command by adding the extra option --domain=js, for example,

$ checkio --domain=js sync checkio_solutions
$ checkio --domain=js run median.js

init and test your repository

In order to work with repositories module GitPython is required

by using checkio tools you can also create your own checkio missions

$ checkio initrepo ~/checkio_mission/new_mission

You can link and push the source of your mission into the github repo

$ checkio linkrepo  ~/checkio_mission/new_mission

After you are done editing the mission, you test your mission by using the command

$ checkio checkrepo ~/checkio_mission/new_mission

and open in your browser.
