Question

我有一个脚本，我试图抓住一个并不总是在那里的密钥的价值。我的IF声明存在问题。这是If Shotype is not None我希望刮掉次要类型，这是一种射击，只有当射击发生时才会出现。

脚本：

import csv
import requests
import os

req = requests.get('https://statsapi.web.nhl.com/api/v1/game/2017010001/feed/live')
data = req.json()

my_data = []
pk = data['gameData']['game']['pk']
for item in data['liveData']['plays']['allPlays']:
    players = item.get('players')
    if players:
        player_a = players[0]['player']['fullName'] if len(players) > 0 else None
        player_b = players[1]['player']['fullName'] if len(players) > 1 else None
        player_c = players[2]['player']['fullName'] if len(players) > 2 else None
        player_d = players[3]['player']['fullName'] if len(players) > 3 else None
    else:
        player_a, player_b, player_c, player_d = None, None, None, None
        if  shotype is not None:
            shotype = item['result']['secondaryType']
            event = item['result']['event']
            shotype = item['result']['secondaryType']
            time = item['about']['periodTime']
            Tm = item.get('team', {}).get('triCode')
            coordinates_x, coordinates_y = item['coordinates'].get('x'), item['coordinates'].get('y')

my_data.append([pk, player_a, player_b, player_c, player_d, event, shotype, time, Tm, coordinates_x, coordinates_y])

headers = ["pk", "player_a", "player_b", "player_c", "player_d", "event", "shotype", "time", "Tm", "coordinates_x", "coordinates_y"]

with open('NHL_' + str(pk) + '_Indv_PBP.csv', "a", newline='') as f:
    writer = csv.writer(f)
    writer.writerow(headers)
    writer.writerows(my_data)
f.close()

您应该在分配后检查shotype 。我相信你想要的是检查字典是否有特定的关键字，所以只需：

player_a, player_b, player_c, player_d = None, None, None, None if 'result' in item: result = item['result'] if 'secondaryType' in result: shotype = result['secondaryType'] event = result['event'] if 'about' in item: about = item['about'] if 'periodTime' in about: time = about['periodTime'] # ... and so on

Python - 如果_不是None：
