我发现了几个这方面的主题,我找到了这个解决方案:
sentence=re.sub(ur"[^\P{P}'|-]+",'',sentence)
这应该删除除了'之外的每个标点符号,问题是它还会删除句子中的所有其他标点符号.
例:
>>> sentence="warhol's art used many types of media, including hand drawing, painting, printmaking, photography, silk screening, sculpture, film, and music."
>>> sentence=re.sub(ur"[^\P{P}']+",'',sentence)
>>> print sentence
'
当然我想要的是保持句子没有标点符号,"warhol"保持原样
期望的输出:
"warhol's art used many types of media including hand drawing painting printmaking photography silk screening sculpture film and music"
"austro-hungarian empire"
编辑:我也试过用
tbl = dict.fromkeys(i for i in xrange(sys.maxunicode)
if unicodedata.category(unichr(i)).startswith('P'))
sentence = sentence.translate(tbl)
但这会删除每个标点符号
