答案 0 :(得分:0)
import re
s = "the cow's milk is a-okay!"
s = re.sub(r'[^a-zA-Z\s-]+', '', s) # remove anything that isn't a letter, space, or hyphen
s = re.sub(r'\s+', '-', s) # replace all spaces with hyphens
print(s) # the-cows-milk-is-a-okay
这里的'空格'是任何空格字符,包括制表符和换行符。要更改此设置,请将\s
替换为实际的空格字符。
多个空格的运行将被单个连字符替换。要更改此设置,请在第二次调用中删除+
re.sub
。

这个怎么样(缺点是无法保持连字符-
),
import string
s = "the cow's milk is a-okay!"
table = string.maketrans(" ", "-")
new_s = s.translate(table, string.punctuation)
print(new_s)
# the-cows-milk-is-aokay

>>> string = "the cow's milk is a-okay!"
>>> string
"the cow's milk is a-okay!"
>>> string = string.replace(' ','-')
>>> for char in string:
... if char in "?.!:;/'":
... string = string.replace(char,'')
...
>>> string
'the-cows-milk-is-a-okay'

可以使用简单的生成器表达式来实现此目的:
>>> s = "the cow's milk is a-okay!"
>>> ''.join(('-' if el == " " else el if el not in "?.!:;/'" else "" for el in s))
'the-cows-milk-is-a-okay'
>>>
