Custom video module need help debugging

[nuckinfutz]

I wrote a module to display a random video based on the successful evaluation of the FacialRecognition module… It executes without any obvious errors but only the following output appears on the mirror.

// helloworld
//module_0_helloworld

I modified the hellowworld module as follows

Module.register("helloworld",{

#!/usr/bin/env python
        import os, random

        def rndvid ():
        randomfile = random.choice(os.listdir("/home/pi/Videos"))
        file = ' /home/pi/Videos/'+ randomfile
        os.system ('omxplayer' + file)

         rndvid ()
}

});

I would love som help
