$12\mathrm{.}12$ LAB: Calculator class

In the file main.py write a class called Calculator that emulates basic functions of a calculator: addition, subtraction, multiplication, division, and clear. The class has one attribute called calc$\_($v$)$alue for the calculator's current value. Implement the following methods as listed below:

Default constructor method to set the attribute to $0\mathrm{.}0$

addition $($self$,$ val$)-$ add the parameter to the attribute

subtraction $($self$,$ val$)-$subtract the parameter from the attribute

multiplication $($self$,$ val$)-$ multiply the attribute by the parameter

division$($self$,$ val$)-$ divide the attribute by the parameter

clear $($self$)-$ set the attribute to $0\mathrm{.}0$

get$\_($v$)$alue $($self$)-$ return the attribute

Given two float input values num$1$ and num$2,$ the program outputs the following values:

$1.$ The initial value of the instance attribute, calc$\_($v$)$alue

$2.$ The value after adding num$1$

$3.$ The value after multiplying by $3$

$4.$ The value after subtracting num$2$

$5.$ The value after dividing by $2$

$6.$ The value after calling the clear$()$ method

Ex: If the input is:

$10\mathrm{.}0$

$5\mathrm{.}0$

the output is:

$0\mathrm{.}0$

$10\mathrm{.}0$

$30\mathrm{.}0$

$25\mathrm{.}0$

$12\mathrm{.}5$

$0\mathrm{.}0$
