Python：从文件中读取推文，没有用户信息

Question

我是 python 新手，正在玩推文。

这可能很愚蠢，但我遇到了关于 tweets 用户实体的问题。好像我正在将 .json 文件读取到 dict 中。我可以在字典中的不同位置打印出推文，例如： 推文 = 推文 [7] 打印（推文）。

code 1

当我打印 print (tweet['entities']) 时，我会看到主题标签之类的东西。 当我打印用户密钥时，它们会显示出来。

code 2

但是，问题是当我尝试遍历并打印出用户内容的内容时，例如屏幕名称、位置等

code3

statuses = []
for tweet in tweets:
    statuses.append(tweet['text']) 

ids = []
for tweet in tweets:
    ids.append(tweet['id_str'])

times = []
for tweet in tweets:
    times.append(tweet['user']['created_at'])

screen_names = []
for tweet in tweets:
    screen_names.append (tweet['user']['screen_name'])

读取json有问题吗？这是文件https://drive.google.com/file/d/1u2soBW4PnRTuCMLdKODf4oKl9Zz88D7l/view?usp=sharing中推文的链接 我只是愚蠢并做了一些可笑的错误吗？非常感谢帮助新手。我环顾四周，找不到有关用户资料不存在的任何信息。抱歉，如果我没有提供帮助所需的所有信息。

代码：

    import json

    import tweepy

    import twitter

    tweets = []

    for line in open('tweets5.json'):

      try: 
        tweets.append(json.loads(line))

    except:
        pass

    print (len(tweets))

    tweet = tweets[2]

    print (tweet)

    print (tweet['entities'])

    print (tweet['user'].keys())

    print (tweet['text'])

    print (tweet['id_str'])

    print (tweet['user']['name'])

    print (tweet['user']['location'])
    print (tweet['place'])
    print(tweet['user']['screen_name'])
    print (tweet['geo'])
    print(tweet['user']['created_at'])

    print (tweet['favorite_count'])
    print (tweet['retweet_count'])


 **//errors start here I get a key error for id_str when I try to do IDs, so I tried moving things around to see if any of them would go through successfully & move on, but I get a key error for whatever is in the brackets first.

statuses = []
for tweet in tweets:
    statuses.append(tweet['text']) 

ids = []
for tweet in tweets:
    ids.append(tweet['id_str'])

times = []
for tweet in tweets:
    times.append(tweet['user']['created_at'])

screen_names = []
for tweet in tweets:
    screen_names.append (tweet['user']['screen_name']) 

这就是推文的样子：

Answer 1

我认为这条线

print (['user']['screen_name'])

应该是：

print(tweet['user']['screen_name'])
