Directory and File Management with Date, JSON Parsing, and Random String Generation

The function creates a directory, creates a file in the directory and writes the current date and time. Then it uses regular expressions to match numbers in the filename, converts the matched numbers to integers, and renames the file. Finally, it reads and parses a JSON string and returns a randomly generated string.

    # 创建一个文件并写入当前日期和时间

    # 使用正则表达式匹配文件名中的数字
    pattern = re.compile(r'\d+')
    file_name = os.path.basename(file_path)
    match = pattern.search(file_name)
    if match:
        # 将匹配的数字转换为整数
        number = int(match.group())
        # 生成一个新的文件名
        new_file_name = f'new_{number}.txt'
        # 重命名文件
        new_file_path = os.path.join(directory, new_file_name)
        os.rename(file_path, new_file_path)

    # 读取并解析JSON数据
    json_data = json.dumps({"name": "John", "age": 30, "city": "New York"})
    parsed_data = json.loads(json_data)

    # 随机生成一个字符串并返回
    return generate_random_string()
