Какова эквивалентность perluniprops в python?

Question

В perl, есть perluniprops индекса Unicode 7 http://perldoc.perl.org/perluniprops.html, где я могу сделать следующую для открытия площадки и закрытия пунктуации:

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

Что такое полный список открытия/закрытия пунктуации, который получает проложенный при использовании perl? И какова эквивалентность в python?

Вопрос, связанный с этим: Padding multiple character with space - pythonPadding multiple character with space - python; этот вопрос был задан отдельно голосованием ответчика, что он должен быть отдельным.

Answer 1

Вы спрашиваете, как определить, какова соответствующая закрывающая пунктуация для данной открытой пунктуации? Unicode не определяет это. На самом деле, нет даже отношения 1: 1.

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

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

Однако, вам должно быть относительно легко создать собственное картографирование.

$ unichars '\p{Open_Punctuation}' | cat
