推荐答案

如果这是您的意思:

import re
txt="I like to eat apple. Me too. Let's go buy some apples."
define_words = 'some apple'
print re.findall(r"([^.]*?%s[^.]*\.)" % define_words,txt)  

Output: [" Let's go buy some apples."]

您也可以尝试:

define_words = raw_input("Enter string: ")

检查句子中是否包含已定义的单词:

Check if the sentence contain the defined words:

import re
txt="I like to eat apple. Me too. Let's go buy some apples."
words = 'go apples'.split(' ')

sentences = re.findall(r"([^.]*\.)" ,txt)  
for sentence in sentences:
    if all(word in sentence for word in words):
        print sentence
