python结构包双 [英] python struct pack double

问题描述

我想在python中将-123.456转换成C双用于网络传输.所以我尝试了这个:

I want to convert -123.456 into a C double for network transmission in python. So I tried this:

struct.pack('d', -123.456)

我得到了这个结果:

'w\xbe\x9f\x1a/\xdd^\xc0'

显然那里有一些十六进制，但是 w、/和 ^ 洒在那里是什么?

Obviously there is some hex in there, but what is with the w, /, and ^ sprinkled in there?

推荐答案

它们分别是w"、/"和^".一些字节序列确实对应于 ASCII 字符.

They are, respectively, a "w", "/", and "^". Some byte sequences do correspond to ASCII characters.
