Python module which can be used to store the details of multiple chess tournaments. Game players can be registered into tournaments, and matches between players can be recorded. Player matches are scheduled using the Swiss pairing system where the goal is to pair (as close as possible) each player with an similar-skilled opponent. Players are ranked according to the number of matches won within a tournament, if the players are tied then they are ranked according to the number of matches won by their opponents.
You'll need the following for your development environment:
- [Python] (http://www.python.org)
- [PostgreSQL] (http://www.postgresql.org/)
- [virtualenv] (https://python-guide.readthedocs.org/en/latest/dev/virtualenvs/#virtualenv) (recommended)
The following assumes you have all of the tools listed above installed.
-
Clone the project:
$ git clone https://github.com/thurstonemerson/swiss-system-tournament.git $ cd swiss-system-tournament -
Create and initialize virtualenv for the project:
$ mkvirtualenv swiss-system-tournament $ pip install -r requirements.txt -
This module has a PostgreSQL backend. The database can be created using the script provided:
$ psql \i tournament.sql
Run unit tests using the test script provided:
$ python tournament_test.py
1. Old matches can be deleted.
2. Player records can be deleted.
Extra credit: Tournament records can be deleted.
Extra credit: After adding a tournament, countTournaments() returns 1.
3. After deleting, countPlayers() returns zero.
