如何在python3中打印匹配字符串的下一行(如果我给了Tea，它也应该打印下一行)

def print_next_line(file_path, target_string):
    with open(file_path, 'r') as file:
        lines = file.readlines()
        for i in range(len(lines)):
            if target_string in lines[i]:
                if i+1 < len(lines):
                    print(lines[i+1].strip())
                else:
                    print("已到达文件末尾")
                break

# 调用示例
file_path = 'example.txt'  # 文件路径
target_string = 'Tea'  # 目标字符串
print_next_line(file_path, target_string)
