在python中输出字符串搜索行

def search_line(string, search):
    index = string.find(search)
    if index != -1:
        lines = string[:index].count('\n') + 1
        return f"字符串'{search}'在第{lines}行"
    else:
        return "未找到指定字符串"

# 示例用法
text = """
Hello, world!
This is a sample text.
Python is awesome.
"""

print(search_line(text, "sample"))  # 输出：字符串'sample'在第2行
print(search_line(text, "Java"))    # 输出：未找到指定字符串
