Learn to write cleaner, more modular, and more scaleable code in Python by gaining a master of Object Oriented Programming (OOP). 

You'll start with the basics of object oriented programming and build up to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way you'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

Learn Object-Oriented Programming in Python

# Problem statement

Write a Python **class** called `Calculator` by completing the tasks below:  

## Task 1
### Initializer
Implement an initializer to initialize the values of `num1` and `num2`.

### Properties

* `num1` 
* `num2`

## Task 2

### Methods

* `add()` is a *method* that returns the sum of `num1`
and `num2`.

* `subtract()` is a *method* that returns the subtraction of `num1` from `num2`.
 
* `multiply()` is a *method* that returns the product of `num1` and `num2`.

* `divide()` is a *method* that returns the division of `num2` by `num1`.



## Input
Pass numbers (integers or floats) in the initializer.

## Output
addition, subtraction, division, and multiplication

## Sample input

``` python
obj = Calculator(10, 94);
obj.add()
obj.subtract()
obj.multiply()
obj.divide()
```
## Sample output
``` python
104
84
940
9.4
```

In this exercise, you have to implement a calculator that can perform addition, subtraction, multiplication, and division.
