One way is to use the struct module.
It has the advantage of allowing selection of big endian(>) or little
endian(<) representation etc. The H symbol can be used for a short
integer - ie 2 bytes...
>>> import struct
>>> b = struct.pack(">H", 279)
>>> b = struct.pack("<H", 279)
Note that Python will print bytes with printable representations as
the character form but the data is still two bytes.
>>> struct.pack("H", 33)
