At offset zero (000000): chr(0x31) + chr(0x32)+ chr(0x33)+ chr(0x33)+ 
chr(0x0a) = '1'+'2'+'3'+'4'+'.' = '1234.'

Does it have to do ANYTHING with Python? If I were you, and it was 
something that must be explained, then I would rather start books about 
programming before asking questions on a mailing list that is not 
related to my question.
