Quickly thrown together shellcode parsing script

shellparse.py

"""
Usage:
  -First assemble the .asm file eg (nasm -f elf test.asm)
  -Then objdump the object file eg (objdump -d -M intel test.o)
  -Execute the script with the bytecode you want parsed eg: 
  ---------------------------------
  python3.7 'ShellParse.py' "31 c0
    50
    68 2f 2f 73 68
    68 2f 62 69 6e
    89 e3
    50
    89 e2
    53
    89 e1
    b0 0b
    cd 80"
  ---------------------------------
  This outputs the following:
  --ShellParse--
  Parsed: "\31\xc0\x50\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\x50\x89\xe2\x53\x89\xe1\xb0\x0b\xcd\x80"
