Reading 3 bytes as an integer

Question

How can I read 3 bytes as an integer?

Does struct module provide something like that?

I can read in 3 bytes and add an extra \\x00 and then interpret it as a 4-b

Answer 1

Another option is to just do the bit shifting yourself.

Big Endian:

ba = # 3 byte bytearray
v = ba[0] << 16 | ba[1] << 8 | ba[2]

Little Endian

ba = # 3 byte bytearray
v = ba[2] << 16 | ba[1] << 8 | ba[0]
