- add typer-based CLI to build_season_schedule.py for structured option handling - refactor compute_ratings.py to remove argparse and support typer CLI - improve typing and option descriptions in compute_ratings.py main function - add .gitignore entry for __pycache__ - add requirements.txt with dependencies for the project

# build_season_schedule.py
|
||
#
|
||
# Build a deduped season schedule from SportsEngine team-instance printable pages.
|
||
# - Assumes team-instance schedule pages are TEAM-FIRST for scores.
|
||
# - Determines home/away using the '@' marker on the opponent cell.
|
||
# - Deduplicates primarily by game_id (from /game/show/<id> links), otherwise by a fallback key.
|
||
# - Optionally fetches each game's time from the /game/show/<id> page ("tab_boxscores_content").
|
||
#
|
||
# Usage:
|
||
# pip install requests beautifulsoup4 python-dateutil
|
||
# python build_season_schedule.py --subseason 942425 --teams teams.json --out season_schedule.csv
|
||
#
|
||
# Example teams.json (array):
|
||
# [
|
||
# {"teamName":"Carol Stream Cheaties","team_id":"8944347","team_slug":"carol-stream-cheaties","subseason_id":"942425","instance_id":"10119604"},
