Replace

    ps.close

with

    ps.close()

ps.close is a function object. If you type ps.close at the interpreter you
get a string representation of the function, something like

    <function close at 0xa02df2c>

If you include it in a .py file it does nothing.

To *invoke* a function, you need the parentheses.

Been there done that.
