You need to read the arfguments before calling the exe. Then create 
the full
command string and pass that tro os.system.

However os.system is a blunt instrument, you will find you have much 
more
control using the subprocess module which supercedes os.system and
various others ways of executing external programs. It take a wee bit
more effort but the extra control is worth it.

The documentation  has numerous examples and the "Using the OS"
topic of my tutorial has some info too.
