Question

我正在尝试将推文的标签存储在一个文件中，同时我在终端上打印这些标签并且它工作正常，但标签不存储在文件中。

这是我的代码......

import requests
import json

username = "****"
password = "****"

def start():
    header = { 'Content-Type':'application/json',}

    parameters = {
        ('version','2017-02-27'),
    }

    url = 'https://gateway.watsonplatform.net/natural-language-understanding/api/v1/analyze'

    tw = open('/home/darkhorse/Desktop/ML/refine_tweets.csv','r')
    labeling = open('/home/darkhorse/Desktop/ML/tweets_label.csv','w')
    for tweet in tw:
        Data = { "text":tweet,"features":{ "sentiment":{"document":True } } }
        # changing Data dict to str form
        Data = json.dumps(Data)

        r = requests.post(url, headers=header, params=parameters, data=Data, auth=(username, password))

        # r.content is a byte object so there is need to change it into str
        str_obj =r.content.decode("utf-8")

        # changing str to python obj dict.
        py_obj = json.loads(str_obj)

        try:
            print(py_obj["sentiment"]["document"]["label"])
            labeling.write(py_obj["sentiment"]["document"]["label"])
            labeling.write('\n')
        except:
            print('error')
            # labeling.write('error\n')

    labeling.close()
    tw.close()


if __name__ == '__main__':
    start()

以下是前12条推文及其标签是..
