simple python calculator

#Store number variables for the two numbers

#the sum of the two numbers variable
sum = float(num1) + float(num2)
sum2 = float(num1) - float(num2)
sum3 = float(num1) * float(num2)
sum4 = float(num1) / float(num2)

#what operator to use
choice = input('Enter an operator, + = addition, - = subtraction, * = multiplication and / = division: ')
#different sums based on the operators
if choice == '+':
