con=1
while con==1:
	no1=int(input("Enter First Value "))
	no2=int(input("Enter Second Value "))
	print("Choice")
	print("1. Add")
	print("2. Subtract")
	print("3. Multiplication")
	print("4. Division")
	choice=int(input("Enter Choice "))

def Add():
	return (no1+no2)
def Sub():
	return (no1-no2)
def Mul():
	return (no1*no2)
def Div():
	return (no1/no2)

def perform_op(choice):
	if choice == 1:
		print(Add())
	elif choice == 2:
		print(Sub())
	elif choice == 3:
		print(Mul())
	elif choice == 4:
		print(Div())
	else:
		print("*** Invalid Choice ***")
