python代码，用于比较句子对，并查看它们是否在文本文件中的相同或不同块中

def compare_sentences(sentence1, sentence2, file_path):
    # 读取文本文件内容
    with open(file_path, 'r') as file:
        text = file.read()

    # 判断句子是否在相同块中
    if sentence1 in text and sentence2 in text:
        return "句子在相同块中"
    # 判断句子是否在不同块中
    elif sentence1 not in text and sentence2 not in text:
        return "句子在不同块中"
    else:
        return "句子在不同块中"

# 示例用法
sentence1 = "This is sentence 1."
sentence2 = "This is sentence 2."
file_path = "text_file.txt"
result = compare_sentences(sentence1, sentence2, file_path)
print(result)
