Find and write the output of the following Python code :
class ITEM:
def __init__(self,I=101,N='Pen',Q=10): #constructor
self.Ino=I
self.IName=N
self.Qty=int(Q);
def Buy(self,Q):
self.Qty = self.Qty + Q
def Sell(self,Q):
self.Qty -= Q
def ShowStock(self):
print self.Ino,':',self.IName,'#',self.Qty
I1=ITEM()
I2=ITEM(100,'Eraser',100)
I3=ITEM(102,'Sharpener')
I1.Buy(10)
I2.Sell(25)
I3.Buy(75)
I3.ShowStock()
I1.ShowStock()
I2.ShowStock()
