Struct Endianness in Python

Also: If you don't specify a byte order character, the size of fields is platform dependant!

> Turns out Python can tell you if you are big-endian or little-endian like this:

sys.byteorder

Cool. Handy way to do a quick check. I didn't realize Raspbian on Pi is little-endian.

Most I've used struct is with XBee ZigBee protocol, which uses big-endian.

I literally used this module in a project at my day job. We had to deal with geospatial data in WKB representation, a binary format that supports both endiannesses. Turns out deserializing that data as a struct is easier than dealing with wild bits *shrug*

The fact that Python let’s you pick byte order so easily has saved my skin bunches of times. Great article.

Ow, good to know.

int.to_bytes and bytes.to_int requires a byteorder argument, curious that struct doesn't
