如何使用Python提取当前句子和特定单词周围的句子？

import re

def extract_sentences(text, word, window_size):
    # 使用正则表达式将文本分割成句子
    sentences = re.split(r'(?<!\w\.\w.)(?<![A-Z][a-z]\.)(?<=\.|\?)\s', text)
    
    extracted_sentences = []
    for sentence in sentences:
        # 使用正则表达式匹配特定单词
        if re.search(r'\b{}\b'.format(word), sentence):
            # 获取特定单词在句子中的位置
            word_index = sentence.index(word)
            
            # 提取特定单词周围的句子
            start_index = max(0, word_index - window_size)
            end_index = min(len(sentence), word_index + len(word) + window_size)
            extracted_sentence = sentence[start_index:end_index]
            
            extracted_sentences.append(extracted_sentence)
    
    return extracted_sentences

# 示例用法
text = "Python是一种通用的、解释型的高级编程语言。它具有简洁、易读的语法，适用于各种领域的开发。Python可以用于Web开发、数据分析、人工智能等领域。"
word = "Python"
window_size = 5

result = extract_sentences(text, word, window_size)
for sentence in result:
    print(sentence)
