python - 每次有标点符号时将字符串拆分成句子，标点符号？

Question

我想将字符串拆分为列表中的单独句子。

例子:

string = "Hey! How are you today? I am fine."

输出应该是:

["Hey!", "How are you today?", "I am fine."]

Answer 1

您可以使用内置的正则表达式库。

import re
string = "Hey! How are you today? I am fine."
output = re.findall(".*?[.!\?]", string)

output>> ['Hey!', ' How are you today?', ' I am fine.'] 

更新:

您可以使用 split()方法，但它不会返回用于拆分的字符。

import re
string = "Hey! How are you today? I am fine."
output = re.split("!|?", string)
output>> ['Hey', ' How are you today', ' I am fine.']

如果这对您有用，您可以使用 replace()和 split() .

string = "Hey! How are you today? I am fine."
output = string.replace("!", "?").split("?")
