AttributeError: 'list' object has no attribute 'hbp' #65

AttributeError: 'list' object has no attribute 'hbp'

^ Getting this error on the player stats object

    for game in games:
        stats = mlbgame.team_stats(game.game_id)
        player_stats = mlbgame.player_stats(game.game_id)
        hbp_home = player_stats.home_batting.hbp

Also is there a way to grab or calculate advanced sabermetrics like wRC, FIP, wOPA, etc for teams(not players) on a game level basis. I am working on some ML models and that would be really helpful. Would do any API work myself just want to know if it can be done.

MLB doesn't provide this info as a team stat. You will have to calculate it per player:

player_stats = mlbgame.player_stats(game.game_id)
hbp_home = sum([ p.hbp for p in player_stats.home_batting ])

Sabremetrics would have to be calculated based on individual statistics and then summed. Fangraphs has some information on how to calculate stats like wRC, FIP, and wOPA. You should be able to build arrays and then build list comprehension summations from those individual stats.
