python estimator program code example

Example 1: 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))

Example 2: python calculator

# simple calculator
try:
  # prompt user
    num1 = float(input("Please Enter The first number: "))
    operator = input("Please choose the operator (+) for addition, (-) for subtraction, (*) for multiplication"
                     "(/) for division , (%) for remainder: ")
    num2 = float(input("Please Enter The second number: "))
    
    if operator == '+':
        result = num1 + num2
        print("The result is: ", result)
    elif operator == '-':
        result = num1 - num2
        print("The result is: ", result)
    elif operator == '*':
        result = num1 * num2
        print("The result is: ", result)
    elif operator == '/':
        try:
            if True:
                result = num1 / num2
                print(result)
        except ZeroDivisionError as err:
            print(err, " oops! zero division occur ")
    elif operator == '%':
        if operator == '%':
            result = num1 % num2
            print("The result is: ", result)
    else:
        raise TypeError


except ValueError:
