 needs to be converted right after loading. But I'm new to Python the f.rea=
dline(s) command, according to the 2.7.3 tutorial and manual, is pretty muc=
h all there is for file i/o. If, as you indicated, f.readlines() is depreca=
ted then what should I use instead? I'm using ver. 2.6 on Linux (it's a bit=
 dated, I know).

Just iterate over the file directly using a for-loop (e.g. `for line
in some_file:`). Each iteration yields one line of the file. I used a
very minor variation of this approach in my code (a list comprehension
is just syntax sugar for a for-loop).
