Python code for an Empty object to Add all cells of object ( obtained by using Cell Fracture ) on Left Mouse Click event

By using cell Fracture, I broken down a plane named ‘glass’ into 80 sub parts having names

glass_cell.001,
glass_cell.002,
glass_cell.003,
.
upto
.
glass_cell.080

I’ve tried it using loop as follow…

def shoot(cont):
own = cont.owner
scene = own.scene
mouse = cont.sensors[‘MOUSE_BRICK_NAME’]

if mouse.positive:             
    for i in range(0,80):
        if i==0:
            scene.addObject('glass_cell','Empty', 360)
        else
            if i<10:
                scene.addObject('glass_cell.00'+i,'Empty', 360)
            elif i<100:
                scene.addObject('glass_cell.0'+i,'Empty', 360)
            else:
                scene.addObject('glass_cell.'+i,'Empty', 360)

But it’s not working.
Please Help.
