Answers for "python code 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))

how to make a calculator in python

# This will be one of the most advanced results you will find.

# We will be using classes and simple operators like +,-,*,/

class Calculator:
  def addition(a,b):
    return a + b

  def subtraction(a,b):
    if a<b:
      return b - a
    else:
      return a - b

  def multiplication(a,b):
    return a * b

  def division(a,b):	
    if a<b:
      return b / a
    else:
      return a / b

# You can do this in terminal.
<C:/Users/username>python
>>> from main import Calculator
>>> result = Calculator.[addition|subtraction|multiplication|division](anyNumber, anyNumber)
>>> print(result)
