📝 Walkthrough

Walkthrough

The changes update DataFrame conversion, Retrosheet GitHub authentication, Baseball-Reference team data parsing, team results handling, and future-season team ID lookup.

Changes

DataFrame conversion

Layer / File(s) Summary
Column conversion and validation
pybaseball/datahelpers/postprocessing.py, pybaseball/team_game_logs.py, tests/pybaseball/test_team_game_logs.py, tests/pybaseball/test_statcast.py
Numeric conversion now runs one column at a time and leaves a column unchanged when conversion raises ValueError or TypeError. The Statcast fixture stores parsed dates and retains existing values when parsing fails.

Retrosheet GitHub client setup

Layer / File(s) Summary
Conditional GitHub authentication
pybaseball/retrosheet.py, tests/pybaseball/test_retrosheet.py
Retrosheet lookups use Auth.Token when GH_TOKEN is set and Github() when it is empty. Tests check the events call arguments and exception propagation for both cases.

Team data retrieval

Layer / File(s) Summary
Batting and pitching table parsing
pybaseball/team_batting.py, pybaseball/team_pitching.py, tests/pybaseball/data/team_batting_bref.html, tests/pybaseball/data/team_pitching_bref.html, tests/pybaseball/test_team_batting.py, tests/pybaseball/test_team_pitching.py
The parsers select their respective standard-stat tables and read headings from each table header. Fixtures and tests cover parsed results and missing tables.
Team request validation and attendance conversion
pybaseball/team_fielding.py, pybaseball/team_results.py, tests/pybaseball/test_team_fielding.py, tests/pybaseball/data/team_results.html, tests/pybaseball/test_team_results.py
Fielding rejects reversed season ranges and uppercases team abbreviations before building request URLs. Team results assigns converted attendance values back to the column.

Team ID lookup

Layer / File(s) Summary
Future-season lookup behavior
pybaseball/teamid_lookup.py, tests/pybaseball/test_teamid_lookup.py
For seasons beyond the bundled data, team_ids copies the latest year’s rows and updates yearID. From 2025 onward, copied Athletics rows use ATH for teamIDBR and teamIDretro.

Retrosheet lookups may fail on installations using an older permitted PyGithub version. Confirm the supported version and update the dependency floor before merging.

Raise the PyGithub minimum version to match the Auth import.

from github import Auth and Auth.Token require PyGithub 1.59 or newer. setup.py still declares pygithub>=1.51. With an older version, importing pybaseball.retrosheet can raise ImportError.

🐛 Suggested fix
-                      'pygithub>=1.51',
+                      'pygithub>=1.59',

…erence HTML (jldbc#461)

Baseball Reference changed their table IDs:
- team_batting -> players_standard_batting
- team_pitching -> players_standard_pitching

Also make header extraction dynamic instead of hardcoded slice indices.
The bundled CSV data ends at 2021 because the upstream Lahman/Retrosheet
data hasn't been updated. Since MLB team composition hasn't changed,
extrapolate from the last known year when a more recent season is requested.
