Python-Unicode和双反斜杠 [英] Python - Unicode & double backslashes

问题描述

我用BeautifulSoup抓取了一个网页.在得到文本之后，除了列表的部分如下所示，我得到了很好的输出:

I scrapped a webpage with BeautifulSoup. I got great output except parts of the list look like this after getting the text:

list = [u'that\\u2019s', u'it\\u2019ll', u'It\\u2019s', u'don\\u2019t', u'That\\u2019s', u'we\\u2019re', u'\\u2013']

我现在的问题是如何摆脱这些双反斜杠或将其替换为特殊字符.

My question now is how to get rid or replace these double backslashes with the special characters they are.

如果我先打印示例列表的第一元素，则输出看起来像

If i print the first the first element of the example list the output looks like

print list[0]
that\u2019s

我已经阅读了许多有关此主题的其他问题/线索，但最终变得更加困惑，因为我是正在考虑unicode/编码/解码的初学者.

I already read a lot of other questions / threads about this topic but I ended up being even more confused, as I am a beginner considering unicode / encoding / decoding.

我希望有人可以帮助我解决这个问题.

I hope that someone could help me with this issue.

谢谢！MG

推荐答案

这里的问题是该站点最终对那些unicode参数进行了双重编码，只需执行以下操作:

the problem here is that the site ended up double encoding those unicode arguments, just do the following:

ls = [u'that\\u2019s', u'it\\u2019ll', u'It\\u2019s', u'don\\u2019t', u'That\\u2019s', u'we\\u2019re', u'\\u2013']

ls = map(lambda x: x.decode('unicode-escape'), ls)

现在您有了一个包含正确的unicode编码字符串的列表:

now you have a list with properly unicode encoded strings:

for a in ls:
   print a
