探索 NBA 数据¶

我们首先安装 Goldsberry 包,项目源地址:

https://github.com/bradleyfay/py-Goldsberry

使用 pip 安装:

  1. pip install py-goldsberry

该包的接口与 pandas 兼容,可以与 pandasDataFrame 一起使用。

In [1]:

  1. import goldsberry as gb
  2. import pandas as pd

当前使用的版本号为:

In [2]:

  1. gb.__version__

Out[2]:

  1. '0.8.0.1'

球员信息¶

获得 2015-2016 赛季运动员的名单:

In [3]:

  1. players = gb.PlayerList().players()
  2. players = pd.DataFrame(players)
  3.  
  4. players.head()

Out[3]:

球员总数为:

In [4]:

  1. print len(players)
  1. 464

通过查询特定的 TEAM_ABBREVIATION,我们可以查看某个球队本赛季的球员,比如 2014-2015 赛季的总冠军金州勇士 GSW

In [5]:

  1. gsw_players = players.ix[players["TEAM_ABBREVIATION"] == "GSW"]
  2.  
  3. gsw_players[["DISPLAY_LAST_COMMA_FIRST", "FROM_YEAR", "TEAM_ABBREVIATION", "TEAM_CITY", "TEAM_NAME", "PERSON_ID"]]

球员比赛数据¶

通过 DISPLAY_LAST_COMMA_FIRST,我们来查询宣布本赛季之后退役的科比布莱恩特(Kobe, Bryant)的信息:

In [6]:

  1. kobe = players.ix[players["DISPLAY_LAST_COMMA_FIRST"].str.contains("Kobe")]
  2.

为了方便,我们将 KobeID 放到变量中去:

In [7]:

  1. kobe_id = 977

我们来看本赛季 Kobe 的比赛记录:

In [8]:

  1. kobe_logs = gb.player.game_logs(kobe_id)
  2.  
  3. kobe_logs = pd.DataFrame(kobe_logs.logs())
