python中perluniprops的等价物是什么?

本文介绍了python中perluniprops的等价物是什么?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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

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:用空格填充多个字符 - python 用空格填充多个字符 - python;这个问题是由回答者投票分开提出的，它应该分开.

解决方案

您是否在询问如何确定给定的开放标点对应的结束标点是什么?Unicode 没有定义这个.事实上，甚至没有一对一的关系.

$ unichars '\p{Open_Punctuation}' |wc -l75$ unichars '\p{Close_Punctuation}' |wc -l73

但是，您构建自己的映射应该相对容易.

In perl, there's the perluniprops index of Unicode 7, http://perldoc.perl.org/perluniprops.html where I can do the following to pad opening and closing punctuations:

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

What is the full list of opening/closing punctuations that gets padded when using the perl? And what is the equivalence in python?

Related question: Padding multiple character with space - python Padding multiple character with space - python; this question was asked separatedly by answerer's vote that it should be separate.

解决方案

Are you asking how to determine what's the corresponding closing punctuation for a given open punctuation? Unicode does not define this. In fact, there's not even a 1:1 relationship.

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

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

However, It should be relatively easy for you to build your own mapping.

$ unichars '\p{Open_Punctuation}' | cat
