Question

我正在学习Python两个月。我的目标是进行情绪分析！但是自学太难了，所以我想寻求帮助。

我从Twitter API收集数据，然后将数据放到记事本中。这太长了。 {created_at":"Fri Nov 03 03:28:33 +0000 2017", ~~ id, tweet, unicode}

我在IPython控制台（Spyder）上将数据转换为简单数据。这就像"Fri Nov 03 03:46:46 +0000 2017 @user blah blah [hash tags] time stamp"。然后我想再次将简单的数据放到记事本中。代码编写如下。如何更改out_file？

部分的代码

try:
    import json

except ImportError:
    import simplejson as json

tweets_filename = 'C:/Users/ID500/Desktop/SA/Corpus/siri/siri_0.txt' #Not converted data

tweets_file = open(tweets_filename, "r")

for line in tweets_file:
    try:
        tweet = json.loads(line.strip())
        if 'text' in tweet:
            print (tweet['id'])
            print (tweet['created_at'])
            print (tweet['text'])

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

            hashtags = []
            for hashtag in tweet['entities']['hashtags']:
                hashtags.append(hashtag['text'])
            print(hashtags)
            out_file = open("C:/Users/ID500/Desktop/SA/Corpus/final/fn_siri_1.txt", 'a') # I want to put data to that path.
            out_file.write() # What can I write here?
            out_file.close()

    except:
        continue

谢谢！

您可以一次打开两个文件。不要在循环中打开一个

例如

open(tweets_filename) as tweets_file, open(output, "a") as out_file:
    for line in tweets_file:
        # parse the line here 
        out_file.write(line)

我想在Python上使用out_file
