• 如何把6个 by作为单一喷雾剂,使用沙捞中的 st
原标题:How to unpack 6 bytes as single integer using struct in Python

我有以下8个特质:

b x05x00x00x00x00x00x05x00 

我试图利用建筑结构获得两座ger。 无包装:一只是头2个 by,另一套是最后6个 the。 采用:

struct.unpack("<H6B")

但这种回报是

(5, 0, 0, 0, 0, 5, 0)

我想谈谈以下几点:

(5, 5)

我怎样用tes子来看待过去6年的愤怒价值? 我不希望各自为政。

https://docs.python.org/library/struct.html>rel=“nofollow noreferer”>struct 不支持非2人规模的培养。 这很常见。 在您的平台上不支持这种愤怒(住所、借方,但你可以做一系列的工作)。

def unpack48(x):
    x1, x2, x3 = struct.unpack( <HHI , x)
    return x1, x2 | (x3 << 16)
问题回答

The standard struct module doesn t support all possible sizes so you either have to join some bits together yourself (see Dietrich s answer), or you can use external modules such as bitstring.

>>> from bitstring import BitArray
>>> b = BitArray(bytes=b x05x00x00x00x00x00x05x00 )
>>> b.unpack( <H6B )
[5, 0, 0, 0, 0, 5, 0]

这与标准<代码>truct.un Pack相同。 但现在我们可以将第二个项目作为6个无端(48个比值)的无签名人分类:

>>> b.unpack( <H, uintle:48 )
[5, 21474836480]                   

这给你带来了与迪特里希的答复相同的结果,也表明你在你的提问中走过错的路! 这里需要的是:

>>> b.unpack( uintle:48, <H )
[5, 5]

请注意,也可将<代码><H作为<编码>uintle:16 如果你想要更一致的表示。
