Python 从字符串、保留、字母表、数字和标点符号中去除特殊字符

我试图清除字符串中的所有特殊字符，并保留所有其他字符，包括标点符号

mystring = "Q18. On a scale from 0 to 10 where 0 means ‘not at all interested' and 10 means ‘very interested', how interested are you in helping to address problems that affect poor people in poor countries?"

我迄今为止的努力：

newlabel = re.sub('[^A-Za-z0-9]+', ' ', newstring)

输出：

Q18 On a scale from 0 to 10 where 0 means not at all interested and 10 means very interested how interested are you in helping to address problems that affect poor people in poor countries 

Q18. On a scale from 0 to 10 where 0 means not at all interested' and 10 means very interested', how interested are you in helping to address problems that affect poor people in poor countries?

如何在我当前拥有的正则表达式中保留标点符号，或者有更好的解决方案吗？

已解决

print (newstring.decode('unicode_escape').encode('ascii','ignore'))

输出：

Q18 On a scale from 0 to 10 where 0 means not at all interested and 10 means very interested how interested are you in helping to address problems that affect poor people in poor countries 

Q18. On a scale from 0 to 10 where 0 means not at all interested' and 10 means very interested', how interested are you in helping to address problems that affect poor people in poor countries?

解决了,

print (newstring.decode('unicode_escape').encode('ascii','ignore'))

输出：

Q18 On a scale from 0 to 10 where 0 means not at all interested and 10 means very interested how interested are you in helping to address problems that affect poor people in poor countries 

Q18. On a scale from 0 to 10 where 0 means not at all interested' and 10 means very interested', how interested are you in helping to address problems that affect poor people in poor countries?

如果你需要改变的只是保留圆点，那么把它添加到正则表达式中就可以解决这个问题

re.sub('[^A-Za-z0-9\.]+', ' ', mystring)

只需在正则表达式中的每个标点符号之前添加反斜杠…..

您真的在

非常感兴趣的“

之前有unicode字符吗？是的。不知道为什么或者如何，但它就在那里，我想把它去掉：）你真的有那个unicode字符吗。不知道为什么或如何，但它就在那里，我想摆脱它：）你有没有参考其他东西来提出解决方案？一旦你说它们是“独角兽”，我快速搜索了一下，在这里找到了答案：太好了。我把这个问题看作是那个问题的重复。这对未来的读者会很有帮助。你有没有参考其他东西来提出这个解决方案？一旦你说它们是“unicodes”，我就快速搜索了一下，在这里找到了答案：太好了。我把这个问题看作是那个问题的重复。这将对未来的读者有所帮助。
