You can make it simpler by not splitting the input file into lines.
Treat it as a single string.
in_put = open('test.html', 'r').read()
replace_words = ['TWY', 'RWY', 'WIP']
for replace_word in replace_words:
in_put = in_put.replace(replace_word, "<b><font
color='#FF0000'>" + replace_word + "</font></b>")
open('test_highlight.html', 'a').write(in_put)

Thanks Shantanoo,
I like that a lot better. Had to modify it just a little.
replace_words = ['TWY', 'RWY', 'WIP']
for line in in_put:
for replace_word in replace_words:
line = line.replace(replace_word, "<b><font
color='#FF0000'>" + replace_word + "</font></b>")
out_put.write(line)
I can never quite get when to use a nested loop.
Thanks again,
Will
