You need to read about basic string operations.  Try this page of the
tutorial:

         http://www.python.org/doc/tut/node5.html

(or, if you're really interested in learning Python, try the entire
tutorial -- it's well-written and not all that long).

E.g., to see if the first three bytes of the line is "+++" just do

      if myline[:3] =3D=3D "+++":

Simple, no?  And, to contatenate bytes 15-20 to the end of the line, do:=

      myline =3D myline + myline[15:20]

Even simpler!  That's Python for you...

Cheers,
=2D- Joe
