TypeError: can't concat str to bytesz

执行 python eternalblue_exploit8.py 之后报一下错误，不知道问题出在哪儿了。麻烦看看，谢谢

Traceback (most recent call last):
  File "/root/ms17010/eternalblue_exploit8.py", line 58, in <module>
    ntfea9000 = (pack('<BBH', 0, 0, 0) + '\x00')*0x260  # with these fea, ntfea size is 0x1c80
TypeError: can't concat str to bytesz

b\x00 ？应该是哪个字符串前面加一个b，不然就会报错

'\x00'是个字符串，而pack('<BBH', 0, 0, 0)是个字节数组，它们俩不能相加
你到底想干什么
