"删除使用撇号分隔字符串后的空格"

Question

我想用“不能”或“不”的字眼删除空白，无论是通过regex还是在删除时

from nltk.tokenize import WordPunctTokenizer
tok = WordPunctTokenizer()
detok = MosesDetokenizer()

pattern= "[^\w ]+ "
text= "i can ' t use this cause they won ' t fit"
string= re.sub(pattern, '', text)
tk = tok.tokenize(string)
output= detok.detokenize(tk, return_str = True)
print(output)

 "i can 't use this cause they won' t fit"

关于如何在“can”和“won”之后删除空白的任何想法，我都不能也不会。当我使用^{{cd1>}去破坏时，我得到了双空格，一个在撇号前后。示例^{cd2>}

Answer 1

我认为你可以简单地做一些事情，比如：

output = "i can 't use this cause they won' t fit"
output = output.replace(" '", "")
print output
"i can't use this cause they won't fit"

Answer 2

@BenT我不能说regex，但可以在输出上应用以下操作：

output = "i can 't use this cause they won' t fit"
output = "'".join(output.split(" '"))
output = "'".join(output.split("' "))
print(output)
"i can't use this cause they won't fit"
