Getting started

---

NOTE

This package is in early stages of development and the API is likely to change

---

The API contains endpoints which reflect the structure of the understat website. Below is a table showing the different endpoints and the pages on understat.com to which they correspond

Endpoint	Webpage
UnderstatClient.league	https://understat.com/league/<league_name>
UnderstatClient.team	https://understat.com/team/<team_name>/<season>
UnderstatClient.player	https://understat.com/player/<player_id>
UnderstatClient.match	https://understat.com/match/<match_id>

Every mwthod in the public API corresponds to one of the tables visible on the understat page for the relevant endpoint. Each method returns JSON with the relevant data. Below are some examples of how to use the API. Note how the league() and team() methods can accept the names of leagues and teams respectively, but player() and match() must receive an id number.

from understatapi import UnderstatClient

understat = UnderstatClient()
# get data for every player playing in the Premier League in 2019/20
league_player_data = understat.league(league="EPL").get_player_data(season="2019")
# Get the name and id of one of the player
player_id, player_name = league_player_data[0]["id"], league_player_data[0]["player_name"]
# Get data for every shot this player has taken in a league match (for all seasons)
player_shot_data = understat.player(player=player_id).get_shot_data()

from understatapi import UnderstatClient

understat = UnderstatClient()
# get data for every league match involving Manchester United in 2019/20
team_match_data = understat.team(team="Manchester_United").get_match_data(season="2019")
# get the id for the first match of the season
match_id = match_data[0]["id"]
# get the rosters for the both teams in that match
roster_data = understat.match(match=match_id).get_roster_data()

You can also use the UnderstatClient class as a context manager which closes the session after it has been used, and also has some improved error handling. This is the recommended way to interact with the API.

from understatapi import UnderstatClient

with UnderstatClient() as understat:
    team_match_data = understat.team(team="Manchester_United").get_match_data(season="2019")

Contributing

If you find any bugs in the code or have any feature requests, please make an issue and I'll try to address it as soon as possible. If you would like to implement the changes yourself you can make a pull request

• Clone the repo git clone [e-mail]:collinb9/understatAPI
• Create a branch to work off git checkout -b descriptive_branch_name
• Make and commit your changes
• Push your changes git push
• Come back to the repo on github, and click on Pull requests -> New pull request

Before a pull request can be merged the code will have to pass a number of checks that are run using CircleCI. These checks are

• Check that the code has been formatted using black
• Lint the code using pylint
• Check type annotations using mypy
• Run the unit tests and check that they have 100% coverage

These checks are in place to ensure a consistent style and quality across the code. To check if the changes you have made will pass these tests run

pip install -r requirements.txt
pip install -r test_requirments.txt
pip install -r docs_requirments.txt
chmod +x ci/run_tests.sh
ci/run_tests.sh

Don't let these tests deter you from making a pull request. Make the changes to introduce the new functionality/bug fix and then I will be happy to help get the code to a stage where it passes the tests.
