Well, if 0 is out of range, the string is empty; readline() returns 
an empty string when it gets the EOF before any other thing. (You 
learn this by reading the Python documentation).
So, your popen() call gave you an empty file...

>-a")

...which is not a surprise, given that command. You must duplicate 
back quotes inside a string, they are used as escape characters. 
Again, read the Python manuals...
Maybe you should investigate the several popen variants, using echo 
to construct the command is a bit crazy...

Surely! But this is not the problem here.
