如何摆脱python中字符串中的b前缀？

Question

我导入的一堆推文在阅读时出现了这个问题

b'I posted a new photo to Facebook'

我收集b表明它是一个字节。但这被证明是有问题的，因为在我最终编写的CSV文件中，该文件b不会消失并且会干扰将来的代码。

有没有简单的方法可以b从我的文字行中删除此前缀？

请记住，我似乎需要将文本编码为utf-8或tweepy难以将其从网络上提取。

这是我正在分析的链接内容：

https://www.dropbox.com/s/sjmsbuhrghj7abt/new_tweets.txt?dl=0

new_tweets = 'content in the link'

代码尝试

outtweets = [[tweet.text.encode("utf-8").decode("utf-8")] for tweet in new_tweets]
print(outtweets)

错误

您需要解码所需bytes的字符串：

b = b'1234'
print(b.decode('utf-8'))  # '1234'
