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：

pip install py-goldsberry 

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

In [1]:

import goldsberry as gb
import pandas as pd

当前使用的版本号为：

In [2]:

gb.__version__

Out[2]:

'0.8.0.1'

球员信息

获得 2015-2016 赛季运动员的名单：

In [3]:

players = gb.PlayerList().players()
players = pd.DataFrame(players)

players.head()

Out[3]:

	DISPLAY_LAST_COMMA_FIRST	FROM_YEAR	GAMES_PLAYED_FLAG	PERSON_ID	PLAYERCODE	ROSTERSTATUS	TEAM_ABBREVIATION	TEAM_CITY	TEAM_CODE	TEAM_ID	TEAM_NAME	TO_YEAR

球员总数为：

In [4]:

print len(players)

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]:

gsw_players = players.ix[players["TEAM_ABBREVIATION"] == "GSW"]

gsw_players[["DISPLAY_LAST_COMMA_FIRST", "FROM_YEAR", "TEAM_ABBREVIATION", "TEAM_CITY", "TEAM_NAME", "PERSON_ID"]]

Out[5]:

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]:

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

kobe

Out[6]:

	DISPLAY_LAST_COMMA_FIRST	FROM_YEAR	GAMES_PLAYED_FLAG	PERSON_ID	PLAYERCODE	ROSTERSTATUS	TEAM_ABBREVIATION	TEAM_CITY	TEAM_CODE	TEAM_ID	TEAM_NAME	TO_YEAR
64	Bryant, Kobe	1996	Y	977	kobe_bryant	1	LAL	Los Angeles	lakers	1610612747	Lakers	2015

为了方便，我们将 Kobe 的 ID 放到变量中去：

In [7]:

kobe_id = 977

我们来看本赛季 Kobe 的比赛记录：

In [8]:

kobe_logs = gb.player.game_logs(kobe_id)

kobe_logs = pd.DataFrame(kobe_logs.logs())

# 最近五场比赛
kobe_logs.head()
