Answers for "how to make a python calculator"

simple python calculator

#Store number variables for the two numbers

num1 = input('Enter first number: ')
num2 = input('Enter second number: ')

#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 == '+':
  print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

  if choice == '-':
    print('The sum of {0} and {1} is {2}'.format(num1, num2, sum2))

if choice == '*':
    print('The sum of {0} and {1} is {2}'.format(num1, num2, sum3))

if choice == '/':
    print('The sum of {0} and {1} is {2}'.format(num1, num2, sum4))
