Hi,
I'm trying to nest the "info_header", "info_body", and "info_trailer" structs
(see below) into a "data_packet" struct. Does anyone know how I can/should
accomplish this? Thanks.
batch_header_format = struct.Struct('!c2h')
info_header_format = struct.Struct('!2hl')
mkt_status_format = struct.Struct('!c')
info_trailer_format = struct.Struct('!hc')
mkt_session_codes = [b'PO',b'PC',b'CO',b'CC',b'CK',b'CL']
mkt_type = [b'N',b'S',b'O',b'A',b'C',b'G']
batch_header = batch_header_format.pack(b'1',1,1024)
total_size = info_header_format.size + mkt_status_format.size +
info_trailer_format.size
# Combine following into data struct.
info_header =
info_header_format.pack(int(binascii.hexlify(mkt_session_codes[random.randint(0,5)])),
total_size, 124)
info_body = mkt_status_format.pack(mkt_type[random.randint(0,5)])
info_trailer = info_trailer_format.pack(0, b'\r')
