I agree that there's no point in loading a file into a format which only needs to be converted right after loading. But I'm new to Python the f.readline(s) command, according to the 2.7.3 tutorial and manual, is pretty much all there is for file i/o. If, as you indicated, f.readlines() is deprecated 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). Cheers, Chris
