made a calculator

if symb == "+":

elif symb == "-":
print("Answer =",num1-num2)
elif symb == "*":
print("Answer =",num1*num2)
elif symb == "/":
if num2 != 0: #not to get an infinite loop as anything divided by zero is not defined
print("Answer =",num1/num2)
else:
print("Not defined as the num1 is divided by zero")
else:
print("invalid symb")

print()
print("Calculate anything else, I'm thee for you")
