我们在计划中遵循以下三个主要步骤:
- 授权twitter API客户端。
- 向Twitter API发出GET请求以获取特定查询的推文。
- 解析推文。将每条推文分类为正面,负面或中立。
- 首先,我们创建一个TwitterClient类。该类包含与Twitter API交互和解析推文的所有方法。我们使用__init__函数来处理API客户端的身份验证。
- 在get_tweets函数中,我们使用:fetched_tweets = self.api.search(q = query,count = count)
调用Twitter API来获取推文。 - 在get_tweet_sentiment中,我们使用textblob模块。analysis = TextBlob(self.clean_tweet(tweet))
