只是发布这个,所以我可以稍后搜索它,因为它似乎总是让我感到困惑:

$ python3.2

>>> import curses
>>> print(curses.version)
b'2.2'
>>> print(str(curses.version))
b'2.2'
>>> print(curses.version.encode('utf-8'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'bytes' object has no attribute 'encode'
>>> print(str(curses.version).encode('utf-8'))
b"b'2.2'"

问题:如何bytes在Python 3中打印二进制()字符串,没有b'前缀？

我正在导入的一堆推文在他们阅读时遇到了这个问题

b'I posted a new photo to Facebook'

我收集b指示它是一个字节.但这证明是有问题的,因为在我最终编写的CSV文件中,b它不会消失,并且会干扰未来的代码.

有没有一种简单的方法可以b从我的文本行中删除这个前缀？

请记住,我似乎需要将文本编码为utf-8或tweepy,无法将其从网络中提取出来.

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
