python - JSON 格式的 "TypeError: list indices must be integers, not str"

Question

好吧，我在尝试让我的代码正常工作时遇到了麻烦，我的目标是创建一个 Reddit 机器人，它引用 Steam 的 appid JSON，以便在用户说出游戏名称时将用户链接到 Steam 商店页面。

机器人几乎完成了，但是，当机器人运行时，我不断收到“TypeError:列表索引必须是整数，而不是 str”。

这是我的代码:

import praw
import time
import json
import codecs

# Death Zone /// I hope you have coffee, brcause you won't leave until this is done

with open('API.json', encoding='utf-8-sig') as steam_strings:
    dic = json.loads(steam_strings.read())
    print("Successfully read JSON")


a = dic.get('appid')
n = dic.get('name')

[app['name'] for app in dic['applist']['apps']['app']]


# End Death Zone


app_id = 'CENSORED'
app_secret = 'CENSORED'
app_uri = 'https://127.0.0.1:65010/authorize_callback'
app_ua = 'Stop asking me how to get the Windows flair dummy, I am here for that reason'
app_scopes = 'account creddits edit flair history identity livemanage modconfig modcontributors modflair modlog modothers modposts modself modwiki mysubreddits privatemessages read report save submit subscribe vote wikiedit wikiread'
app_account_code = 'CENSORED'
app_refresh = 'CENSORED'

import praw
def login():
    r = praw.Reddit(app_ua)
    r.set_oauth_app_info(app_id, app_secret, app_uri)
    r.refresh_access_information(app_refresh)
    print("Steam Link Bot! Version Alpha 0.1.2")
    return r

r = login()


words_to_reply = dic['applist']['apps']['app']['name']


# {'applist':1,'apps':2, 'app':3, 'name':4}

cache = []



def run_bot():
    subreddit = r.get_subreddit("eegras")
    comments = subreddit.get_comments(limit=100)
    for comment in comments:
        comment_text = comment.body.lower()
        isMatch = any(string in comment_text for string in words_to_reply)
        if comment.id not in cache and isMatch:
            comment.reply(['applist']['apps']['app']['appid'])
            cache.append(comment.id)
            print("I replied to a comment successfully!")



while True:
    run_bot()
    time.sleep(10)

任何帮助将不胜感激，我是Python的初学者，所以放轻松。

当通过字符串访问列表时，会引发此类错误，尤其是允许通过字符串索引的字典。

如果可能出现此错误的注释行，或者您可以检查数据类型，制作打印类型并检查它是否确实是字典。但是请确保 JSON 的结构确实像字典一样，或者内部是否有列表。
