Python：从文件读取推文，无用户信息

Question

I'm new to python and playing with tweets.

This may be stupid, but I'm running into problems with the tweets user entities. It seems like I am reading the .json file in ok to a dict. I am able to print out tweets in different locations in the dict, such as: tweet = tweets[7] print (tweet).

code 1

When I print print (tweet['entities']) I see hashtags and that kind of stuff. When I print user keys, they show up.

code 2

But, the problem is when I try to iterate through & print out the contents of user stuff like screen name, location, etc

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'])

Is it a problem with reading in the json? Here is a link to what the tweets look like in the file https://drive.google.com/file/d/1u2soBW4PnRTuCMLdKODf4oKl9Zz88D7l/view?usp=sharing Am I just dumb and doing something ridiculously wrong? Thanks so much for helping a newbie. I looked around and couldnt find anything about the user stuff not being there. Sorry if I didnt give all the info needed to help.

Code:

    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']) 

This is what the tweet looks like:

Answer 1

I think that this line

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

Should be:

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