Python:从文件中读取推文,没有用户信息

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Python:从文件中读取推文,没有用户信息相关的知识,希望对你有一定的参考价值。
我是python的新手并且正在玩推文。
这可能是愚蠢的,但我遇到了推文用户实体的问题。好像我正在读取.json文件中的.json文件。我能够在dict中的不同位置打印出推文,例如:tweet = tweets [7] print(tweet)。
当我打印print(tweet ['entities'])时,我看到了标签和那种东西。当我打印用户密钥时,它们会显示出来。
但是,问题是当我尝试迭代并打印出屏幕名称,位置等用户内容时
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'])
阅读json是一个问题吗?这里有一个链接到文件https://drive.google.com/file/d/1u2soBW4PnRTuCMLdKODf4oKl9Zz88D7l/view?usp=sharing中的推文的样子我只是愚蠢而且做了一些荒谬的错误?非常感谢帮助新手。我环顾四周,无法找到有关用户不在的东西。对不起,如果我没有提供所需的所有帮助信息。
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:

答案
我认为这一行
print (['user']['screen_name'])
应该:
print(tweet['user']['screen_name'])
