处理足球API数据时遭遇'String indices must be integers'错误求助

处理API返回数据时，访问字典出现TypeError: string indices must be integers错误，希望用字符串键访问字典（不使用整数索引，且整数索引会触发越界错误）。

相关代码：

import requests
import json

headers = {
    "X-RapidAPI-Key": "1b6ce2494dmshf74f9c461b4cdbbp1d3b11jsndd6ab0d8575c",
    "X-RapidAPI-Host": "api-football-v1.p.rapidapi.com"
}

url_stats = "https://api-football-v1.p.rapidapi.com/v3/teams/statistics"

qstring_stats1 = {"league":"39","season":"2022","team":"33"}

resp_stats = requests.request("GET", url_stats, headers=headers, params=qstring_stats1)
resp_stats = resp_stats.json()

print(type(resp_stats))
print(resp_stats)

for team in resp_stats["response"]:
    print(str(team["team"]["id"]) + " - " + (team["team"]["name"]))
    print(resp_stats)

输出报错：

<class 'dict'>

{'get': 'teams/statistics', 'parameters': {'league': '39', 'season': '2022', 'team': '33'}, 'errors': [], 'results': 11, 'paging': {'current': 1, 'total': 1}, 'response': {'league': {'id': 39, 'name': 'Premier League', 'country': 'England', 'logo': 'https://media.api-sports.io/football/leagues/39.png', 'flag': 'https://media.api-sports.io/flags/gb.svg', 'season': 2022}, 'team': {'id': 33, 'name': 'Manchester United'}............

Traceback (most recent call last):
  File "E:\Dropbox\CG\Coding\music_api\main.py", line 47, in <module>
    print(str(team["team"]["id"]) + " - " + (team["team"]["name"]))
TypeError: string indices must be integers

从输出的resp_stats结构能看到，resp_stats["response"]是单个字典，不是列表。你用for team in resp_stats["response"]遍历时，实际是在遍历字典的键（比如"league"、"team"这类字符串），此时team变量是字符串，再用team["team"]自然会触发"字符串索引必须是整数"的错误。

直接通过字符串键访问response字典里的team数据即可，不需要循环：

# 替换原来的for循环部分
team_data = resp_stats["response"]["team"]
print(f"{team_data['id']} - {team_data['name']}")

如果后续API可能返回多个结果（即response变成列表），可以先判断类型再兼容处理：

response = resp_stats["response"]
if isinstance(response, list):
    for item in response:
        team_data = item["team"]
        print(f"{team_data['id']} - {team_data['name']}")
else:
    team_data = response["team"]
    print(f"{team_data['id']} - {team_data['name']}")
