If you are on Linux (or other *nix variant) you may be better off
using the shell...

for f in *.dat
do
cat $f >> total.dat
echo "END" >> total.dat
done

Will do it for you.
If you are on Windoze then you need to write a batch file and
then execute it within the for loop so I'd just stick with Python
there.  (Or install cygwin :-)
