Assuming you're talking about "optparse", just prefix the number with "0x"  
on the command line:

python myscript.py -F 0xDEAD

If you don't want to have to type the leading "0x", you'll either have to  
make yourself a custom type for optparse, or treat it as a string and do  
the parsing and error handling afterwards.  My recommendation is that you  
don't do this: not prefixing your constants if they aren't decimal is an  
accident waiting to happen.
