Sorry, but I need to correct you.

First, string.rstrip() might strip unwanted whitespace too; it does
not only strip the newline. You'll need to check wheter the last character
is a newline, and if so, strip it manually, like:

# PSEUDO CODE
for line in lines:
    if line[-1] == '\n':
        line = line[:-1]

Second: f.close is a function, so you'll need to append two parantheses:
f.close()

Third: a one-space indentation is considered Bad Style(tm)

regards,
Gerrit.
