I would guess that this person is coming to python from perl.  In
perl, you are allowed to miss the parens off a method call if it takes
no arguments, so f.close is equivalent to f.close().

I used to make this mistake all the time.  However it is one pychecker
catches, so install pychecker and run it on all your programs is the
answer!
