Hex-text to raw data

# Make from/to text DEADFACE raw data DEADFACE
#
# 1st way
#

import struct

# 1
hex_str = "DEADFACE"

# create int
a = int(hex_str, 16)
b = st.pack("L", a)
# b == '\xce\xfa\xad\xde\x00\x00\x00\x00'

# 2nd way
#

import binascii as b2a

hex_str = "DEADFACE"
res = b2a.unhexlify(hex_str)
# res =='\xde\xad\xfa\xce'


# 3rd way

import binascii as b2a

a = 8037
b = hex(a)
# b == '\x1F65'

b = b[2:].replace("L", "")
# b == '1F65'

res = b2a.unhexlify(b)
# res =='\x1f\x65'
