Yet another Python Implementation of the Elo rating system.

Overview

Python Implementation - Elo Rating System

Yet another Python Implementation of the Elo rating system (how innovative am I right?). Only supports 1vs1 games at the moment. This whole mini-project/library was just made for me to practice my OOP. I also added the ranking system was just for fun.

What is the Elo Rating System?

  • The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor.

How does the Elo Rating System work? How do I calculate Elo?

Examples

Creating an Implementation

from elo_system import *
elo = EloSystem(base_elo = 1000, k = 32) # There are the base values for base_elo and k however you can and may change them

Adding and Removing Players

elo.add_player("John")
elo.add_player("Marcus", 1400)

print(elo.get_overall_list())

elo.remove_player("Marcus")

print(elo.get_overall_list())
[{'player': 'Marcus', 'elo': 1400, 'rank': 'Silver'}, {'player': 'John', 'elo': 1000, 'rank': 'Iron'}]
[{'player': 'John', 'elo': 1000, 'rank': 'Iron'}]

Recording a Match

elo.add_player("John")
elo.add_player("Marcus", 1400)

print(elo.get_overall_list())

elo.record_match("Marcus", "John", "Marcus") # 3rd value is the winner

print(elo.get_overall_list())

elo.record_match("Marcus", "John", "John") # Now the winner is John

print(elo.get_overall_list())

elo.record_match("Marcus", "John") # When the winner is not specified, it is considered a draw

print(elo.get_overall_list())
[{'player': 'Marcus', 'elo': 1400, 'rank': 'Silver'}, {'player': 'John', 'elo': 1000, 'rank': 'Iron'}]
[{'player': 'Marcus', 'elo': 1402, 'rank': 'Silver'}, {'player': 'John', 'elo': 997, 'rank': 'Iron'}] 
[{'player': 'Marcus', 'elo': 1372, 'rank': 'Silver'}, {'player': 'John', 'elo': 1026, 'rank': 'Iron'}]
[{'player': 'Marcus', 'elo': 1359, 'rank': 'Silver'}, {'player': 'John', 'elo': 1038, 'rank': 'Iron'}]

Other Useful Methods

elo.add_player("John")
elo.add_player("Marcus", 2400)
elo.add_player("James", 1000)

# There is also set_elo(), reset_elo(), add_elo() and remove_elo()

print(elo.get_overall_list())

print(elo.get_player_elo("John"))

print(elo.get_player_rank("Marcus"))

print(elo.get_player_count())

print(elo.get_players_with_elo(1000))

print(elo.get_players_with_rank("Silver"))
[{'player': 'Marcus', 'elo': 2400, 'rank': 'Grand Master'}, {'player': 'John', 'elo': 1000, 'rank': 'Iron'}, {'player': 'James', 'elo': 1000, 'rank': 'Iron'}]
1000
