使用Python时出现缩进错误

问题描述

我当前正在尝试使用Python、Elasticearch和Kibana为一个项目发送推文。

在运行我的Python脚本时，我遇到了IndentationError，我不知道为什么，有人能帮助我解决此问题吗？

提前谢谢。

我的Python脚本：

import json
import tweepy
import textblob
import elasticsearch

from tweepy import OAuthHandler, Stream
from tweepy.streaming import StreamListener
from textblob import TextBlob
from elasticsearch import Elasticsearch

consumer_key = '...'
consumer_secret = '...'
access_token = '...'
access_token_secret = '...'

elastic_search = Elasticsearch()

class MyStreamListener(StreamListener):
    def on_data(self, data):
        dict_data = json.loads(data)
        tweet = TextBlob(dict_data["text"])

        print(tweet.sentiment.polarity)

        if tweet.sentiment.polarity < 0:
            sentiment = "negative"
        elif tweet.sentiment.polarity == 0:
            sentiment = "neutral"
        else:
            sentiment = "positive"

        print(sentiment)

        elastic_search.index(index="sentiment",
                 doc_type="test-type",
                 body={"author": dict_data["user"]["screen_name"],
                       "date": dict_data["created_at"],
                       "message": dict_data["text"],
                       "polarity": tweet.sentiment.polarity,
                       "subjectivity": tweet.sentiment.subjectivity,
                       "sentiment": sentiment})

        return True

    def on_failure(self, status):
        print(status)

if __name__ == '__main__':
    listener = MyStreamListener()

    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)

    stream = Stream(auth, listener)
    stream.filter(track=['congress'])

# user_choice = input("Please choose a Hashtag... : ")
# retrieve_tweets = api.search(user_choice)

错误消息：

File "sentiment.py", line 21
    tweet = TextBlob(dict_data["text"])
                                      ^
IndentationError: unindent does not match any outer indentation level

解决方案

您确实有标签。

    def on_data(self, data):
        dict_data = json.loads(data)
# ^ tab and 4 spaces here
        tweet = TextBlob(dict_data["text"])
# ^ 8 spaces here           
        print(tweet.sentiment.polarity)
# ^ ^ two tabs here (equal 16 spaces)

请注意，so Site中的表示形式将制表符转换为空格，但如果将the source复制到代码编辑器中，则会显示制表符：
