newbie problem

I read the other posts after making my own solution to the problem, and
I still like mine better  :-).

Here it is (assuming > python 2.1):

infile = open('inputfilenamehere').readlines()
for line in infile:
  if line[0] == "#":
    key = line.split()[2]
    values = line.split()
    values.insert(0, key)
    print '|'.join(values)

That's about as quick-and-dirty as I could come up with.
If you wanted to write to a file instead of print to the shell, just
replace the last line with:

    outfile.write('|'.join(values) + '\n')

of course after having opened outfile with:

    outfile=open('outputfilenamehere', 'w')

somewhere before the 'for' loop.

Or, redirect your output when you run the program.

Hope this helps (as getting a second opinion almost always helps me).
