Adding data about players on court in NBA games.

Player_on_court package allows you to add to play-by-play data information about players who were on court at any given time.

Important: This package does not request play-by-play data from NBA website. You need to get them in advance, for example, using nba_api package.

How it work

Play-by-play NBA data contains information about each event in the game (throw, substitution, foul, etc.) and players who participated in it (PLAYER1_ID, PLAYER2_ID, PLAYER3_ID).

From this data, we get a list of players who were on court in this quarter. Then, we need to filter this list to 10 people who started quarter. This is done by analyzing substitutions in quarter.

I will soon describe a more complete mechanism for processing play-by-play data to obtain information about players on court in an article.

Code example

>>> from nba_api.stats.endpoints import playbyplayv2
>>> import player_on_court.player_on_court as poc
>>>
>>> pbp = playbyplayv2.PlayByPlayV2(game_id="0022100001").play_by_play.get_data_frame()
>>> pbp_with_players = poc.adding_player_on_court(pbp)
>>> len(pbp_with_players.columns) - len(pbp.columns)
10
>>> players_id = list(pbp_with_players.iloc[0, 34:].reset_index(drop=True))
>>> print(players_id)
[201142, 1629651, 201933, 201935, 203925, 201572, 201950, 1628960, 203114, 203507]
>>> players_name = poc.replace_id_on_name(players_id)
>>> print(players_name)
