CBBpy: A Python-based web scraper for NCAA basketball

Purpose

This package is designed to bridge the gap between data and analysis for NCAA D1 basketball. CBBpy can grab play-by-play, boxscore, and other game metadata for any NCAA D1 men's or women's basketball game. Inspired by the ncaahoopR package by Luke Benz - check that out if you are an R user!

Installation and import

CBBpy requires Python >= 3.9 as well as the following packages:

• pandas>=1.4.2
• numpy>=1.22.3
• python-dateutil>=2.8.2
• pytz>=2022.1
• tqdm>=4.63.0
• lxml>=4.9.0
• joblib>=1.1.0
• beautifulsoup4>=4.11.0
• requests>=2.27.0

Install using pip:

pip install cbbpy

The men's and women's scrapers can be imported as such:

import cbbpy.mens_scraper as s
import cbbpy.womens_scraper as s

Functions available in CBBpy

NOTE: game ID, as far as CBBpy is concernced, is a valid ESPN game ID

s.get_game_info(game_id: str) grabs all the metadata (game date, time, score, teams, referees, etc) for a particular game.

s.get_game_boxscore(game_id: str) returns a pandas DataFrame with each player's stats for a particular game.

s.get_game_pbp(game_id: str) scrapes the play-by-play tables for a game and returns a pandas DataFrame, with each entry representing a play made during the game.

s.get_game(game_id: str, info: bool = True, box: bool = True, pbp: bool = True) gets all information about a game (game info, boxscore, PBP) and returns a tuple of results (game_info, boxscore, pbp). info, box, pbp are booleans which users can set to False if there is any information they wish not to scrape. For example, box = False would return an empty DataFrame for the boxscore info, while scraping PBP and metadata info normally.

s.get_games_season(season: int, info: bool = True, box: bool = True, pbp: bool = True) scrapes all game information for all games in a particular season. As an example, to scrape games for the 2020-21 season, call get_games_season(2021). Returns a tuple of 3 DataFrames, similar to get_game. See get_game for an explanation of booleans info, box, pbp.

s.get_games_range(start_date: str, end_date: str, info: bool = True, box: bool = True, pbp: bool = True) scrapes all game information for all games between start_date and end_date (inclusive). As an example, to scrape games between November 30, 2022 and December 10, 2022, call get_games_season('11-30-2022', '12-10-2022'). Returns a tuple of 3 DataFrames, similar to get_game. See get_game for an explanation of booleans info, box, pbp.

s.get_game_ids(date: Union[str, datetime]) returns a list of all game IDs for a particular date.
