import re

def search_string_in_sentences(target_string, text):
    # 句子分割
    sentences = re.split(r'[.!?]', text)
    matched_sentences = []

    # 匹配句子
    for sentence in sentences:
        if target_string in sentence:
            matched_sentences.append(sentence.strip())

    return matched_sentences

# 示例文本
text = "This is a sample text. It contains multiple sentences. Each sentence is separated by a period. The target string is 'sample'."

# 目标字符串
target_string = "sample"

# 搜索并列出匹配的句子
matched_sentences = search_string_in_sentences(target_string, text)

# 打印匹配的句子
for sentence in matched_sentences:
    print(sentence)
