Random String Generator with File Storage and Output

This function takes two integer arguments, generates a random string of a specified length, stores it in a file, and then reads and outputs this string. It uses multiple built-in libraries to implement different functionalities.

    return ''.join(random.choice(letters) for i in range(length))

def xxx(arg1, arg2):
    # 使用 os, re, time, json, sys, io, random
    # 生成一个指定长度的随机字符串
    if not isinstance(arg1, int) or not isinstance(arg2, int):
        raise ValueError("Both arguments must be integers")
    if arg1 <= 0 or arg2 <= 0:
        raise ValueError("Both arguments must be positive")

    # 使用 os.path.join 创建路径
    path = os.path.join('data', 'random_strings.txt')
    
    # 使用 re 检查字符串是否符合预期格式
    pattern = re.compile(r'^[a-zA-Z0-9]{10}$')

    # 使用 time.sleep 模拟耗时的文件操作
    time.sleep(1)

    # 使用 json 编码和解码字符串
    random_string = generate_random_string(arg1)
    encoded_string = json.dumps({"string": random_string})
    decoded_string = json.loads(encoded_string)['string']

    # 使用 sys.stdout.write 和 io.StringIO 处理输出
    sys.stdout.write("Original string: " + random_string + "\n")
    output = io.StringIO()
    output.write("Decoded string: " + decoded_string + "\n")
    print(output.getvalue())
