python - 如何删除单词之间的标点符号

Question

我使用代码从标点符号中删除一行文本:

line = line.rstrip("\n")
line = line.translate(None, string.punctuation)

问题是像 doesn't 这样的词会变成 doesnt 所以现在我只想删除单词之间的标点符号但似乎找不到办法这样做。如何 我应该这样做吗？

编辑:我考虑过使用 strip() 函数，但它只会对整个句子的右尾和左尾产生影响。

例如:

Isn't ., stackoverflow the - best ?

应该变成:

Isn't stackoverflow the best

代替当前输出:

Isnt stackoverflow the best

Answer 1

假设您将单词视为由空格分隔的字符组:

>>> from string import punctuation
>>> line = "Isn't ., stackoverflow the - best ?"
>>> ' '.join(word.strip(punctuation) for word in line.split() 
             if word.strip(punctuation))
"Isn't stackoverflow the best"

或

>>> line = "Isn't ., stackoverflow the - best ?"
>>> ' '.join(filter(None, (word.strip(punctuation) for word in line.split())))
"Isn't stackoverflow the best"
