This is a draft cheat sheet. It is a work in progress and is not finished yet.
Basic
struct.pack(format, v1, v2, ...) |
struct.unpack(format, string) |
struct.pack_into(format, buffer, offset, v1, v2, ...) |
struct.unpack_from(fmt, buffer[,offset = 0]) |
Examples
pack('hhl', 1, 2, 3) |
b'\x00\x01\x00\x02\x00\x00\x00\x03' |
unpack('hhl', b'\x00\x01\x00\x02\x00\x00\x00\x03') |
