从python中的unicode字符串中删除换行符的问题

Question

我有一段Unicode文本.我想在打印输出之前从文本中删除所有换行符.我的代码看起来像这样:

input_string = u'\u3010JK\u3011\u9032\u5b66\u306b\u56f0\u3063\u305f\uff2a\uff2b\u304c\u5148\u751f\u306b\u52a9\u3051\u3066\u3082\u3089\u3046\u305f\u3081\u306b\uff33\uff25\uff38\uff01.mov'
output_string = ' '.join(input_string.splitlines())
print output_string

我希望库方法能够处理所有脏的换行符unicode字符情况.但是,看起来这个方法不会从给定的输入中删除换行符.请建议一个解决方案,从给定的输入中删除换行符.

Answer 1

根据我的Python,你的字符串不包含类别的Cc字符(控制字符):

>>> unicodedata.category(u'\n') in map(unicodedata.category, input_string)
False

所以这个字符串中没有换行符.unicodedata.name证实了这一点:

>>> for c in s: print unicodedata.name(c)
