If you're running your program under Linux, a very easy way to confirm 
this is to look in the directory

    /proc/<pid>/fd

where <pid> is the PID of your running program. In here you will see a 
symlink to every file your program has open, the name of the link being 
the file descriptor number.

To make it easier to watch, you may want to stick in a sleep of a few 
seconds in-between iterations of the code that executes the Python 
script.

If you see the entries piling up in this directory, that will confirm 
that you're not closing those files.
