TypeError: not all arguments converted during string formatting

Question

经过研究，我找到了一种无需锁定即可读取文件的解决方案。但是我无法从字符串/字符中的描述符解码接收到的缓冲区。这该怎么做？或者是否有另一种选择来读取文件而不阻塞，而不是使用字节？

  filename = '/var/log/auth.log'
    fopen = os.open(filename, os.O_NONBLOCK | os.O_RDONLY)
    while True:
        data = os.read(fopen, 1024)
        if len(data) > 0:
            #logger just for example in code is another function
            logger.info('DATA:   ',data)
            #print data

我收到错误：

Answer 1

默认情况下，您正在传递一个值 data to be formatted into the message, but your message doesn't contain a field for this to be substituted. It follows the printf-style string formatting syntax。

logger.info('DATA: %s', data)
