python - python 中 perluniprops 的等价物是什么？

Question

在 perl 中，有 Unicode 7 的 perluniprops 索引 http://perldoc.perl.org/perluniprops.html我可以执行以下操作来填充开始和结束标点符号:

s/(\p{Open_Punctuation})/ $1 /g;
s/(\p{Close_Punctuation})/ $1 /g;

使用 Perl 时填充的开始/结束标点符号的完整列表是什么？ python 中的等价物是什么？

相关问题:Padding multiple character with space - python Padding multiple character with space - python ;这个问题是根据回答者的投票单独提出的，它应该是单独的。

Answer 1

您是否询问如何确定给定开放标点符号对应的结束标点符号？ Unicode 没有对此进行定义。事实上，甚至不存在 1:1 的关系。

$ unichars '\p{Open_Punctuation}' | wc -l
75

$ unichars '\p{Close_Punctuation}' | wc -l
73

但是，您构建自己的映射应该相对容易。

$ unichars '\p{Open_Punctuation}' | cat

在 python 中使用 cpan Unicode::Tussle 安装 unichars 后:

>>> import subprocess
>>> cmd = "unichars '\p{Open_Punctuation}' | cut -f2 -d' ' | tr -d '\n'"
>>> open_punct = subprocess.check_output(cmd, shell=True).decode('utf8')
Smartmatch is experimental at /usr/local/bin/unichars line 546.
>>> print (open_punct)
