如何使用 python 在 Twitter 上使用主题标签？
谁能告诉我如何在 Python 中使用从 Twitter 检索主题标签？我尝试过使用：
test = api.GetUserTimeline()
for i in test:
text = i.text
hashtag = i.hashtags
print text
print "\n" + hashtag
它返回 hashtag 作为 None，而在文本中它是“life is #wonderful”

据我所知，底层的 Twitter API 实际上并没有为你解析主题标签，python-twitter 包装器也没有。 （当然，我并没有很努力地寻找；））
幸运的是，您自己可以很容易地做到这一点。主题标签是以“#”开头的单词；因此，我们向 Python 询问每个以“#”开头的单词，并删除“#”（即从第二个字符到单词末尾），这些单词来自将文本拆分为单词。 Python 语言几乎比英语语言更清晰：
As far as I can tell, the underlying Twitter API doesn't actually parse out hashtags for you, and neither does the python-twitter wrapper. (Of course, I didn't look very hard ;))
Fortunately, it's pretty easy to do this yourself. Hashtags are words that start with '#'; so we ask Python for each word that starts with '#', with that '#' removed (i.e., from the second character to the end of the word), where the words come from splitting the text into words. It's almost clearer in Python than in English:
