在s/(\p{Open_Punctuation})/ $1 /g;
s/(\p{Close_Punctuation})/ $1 /g;
中，有{7}的python索引，http://perldoc.perl.org/perluniprops.html我可以执行以下操作来填充打开和关闭标点符号：
{{1}}
使用perl时填充的打开/关闭标点符号的完整列表是什么？ {{1}}中的等价性是什么？
相关问题：Padding multiple character with space - python Padding multiple character with space - python;这个问题是由回答者的投票分开询问的，它应该是分开的。
答案 0 :(得分：1)
您是否在询问如何确定给定打开标点符号的相应结束标点符号是什么？ Unicode没有定义这个。事实上，甚至没有1：1的关系。
$ unichars '\p{Open_Punctuation}' | wc -l
75
$ unichars '\p{Close_Punctuation}' | wc -l
73
但是，构建自己的映射应该相对容易。
