将子列表添加到自己的列表中

Question

我正在尝试创建一个程序，从各种网站获取 nba 球队数据，并以列表的形式为每个球队编译统计数据。

即：亚特兰大 = ['107.5','105.6','.516','.543']

数字表示场均得分、对手场均得分、RPI 和篮板率。

我运行现在遇到了一个错误，只是想弄清楚如何接受用户输入，在列表列表中找到该团队的列表，并从该列表中提取特定索引.

import urllib.request
from bs4 import BeautifulSoup

soup = BeautifulSoup(urllib.request.urlopen("http://www.espn.com/nba/stats/rpi"), "lxml")
data = [[x.text for x in row.find_all("td")] for row in soup.select("table tr")]
tables = []
team_s = []
for row in data:
   tables.append(row)
team_s = [item[0] for item in tables]
team_s = [el.replace('\xa0',' ') for el in team_s]   
print (team_s[2])

print ("-" * 80)
print ("Welcome to the NBA betting helper. \nTo start, enter the city of the home team for team 1. Then enter the city of the away team for team 2.")
print ("-" * 80)
home = input("Enter the city of team 1 (Home Team):")
away = input("Enter the city of team 2 (Away Team):")

Atlanta = []
Boston = []


try:
   print (team_s.index("Detroit"))
except ValueError:
   print ("word1 not in list.")

def hometeam():
    print ("ex")        

def awayteam():
    print ("ex")     

#Main

hometeam()
awayteam()

您可以创建一个列表，其中包含每个团队的字典，键作为团队名称，值作为统计列表（RPI、PF、PA）。

>>> soup = BeautifulSoup(urllib.request.urlopen("http://www.espn.com/nba/stats/rpi"), "lxml")
>>> data = [[x.text for x in row.find_all("td")] for row in soup.select("table tr")[2:]]
>>> stats = {team[1]: [team[2], team[8], team[9]] for team in data}
>>> print(stats)

部分输出：

{'Golden State': ['.571', '6853', '6376'], 'Houston': ['.562', '6504', '6007'], 'Toronto': ['.553', '6376', '5892'], 'Boston': ['.543', '6085', '5878'], ...}

请注意，我用 [2:] 分割了 soup.select(...) 列表，因为前 2 个列表不包含球队的统计数据。

其中，字典格式为{'team_name': [RPI, PF, PA]}。我没有添加反弹百分比，因为我在 table 中找不到它。但我相信您可以通过查看上面的代码来添加它。

现在，您可以像这样从用户那里获取输入并打印相应的统计信息：

>>> home = input("Enter the city of team 1 (Home Team): ")
Enter the city of team 1 (Home Team): Boston
>>> print(stats[home])
['.543', '6085', '5878']
