Rewrite the following code in python after removing all syntax error(s). Underline each correction done in the code.

Find and write the output of the following Python code:

STR = ['90','10','30','40']
COUNT = 3
SUM = 0
for I in [1,2,5,4]:
	S = STR[COUNT]

	print SUM
	COUNT-=1

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()
