The code takes two teams of players and matches them up against each-other in a Round-Robin fashion. I recently needed to conduct a Round-Robin tournament between two teams where each player had to match with every other player on the opposing team, but not with his/her teammates.
Fill the teams in two lists in the main function, and the matches will be written to a text file called games.txt. Make sure the teams are of equal size.
Only requirement is numpy. It can be installed using pip:
pip install numpy
