After all the many suggestions (there were many good ones) I found 
something even better in "Python in a Nutshell".  I should have found it 
earlier.  I can do the following:

a = lines.index('my favorite line\n')

and a is the index of lines where "my favorite line' is located.  I 
hadn't seen this earlier, but it suits my purposes perfectly.
Thanks for everyone's suggestions,
Jeremy
