In the file main.py write a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one attribute called value for the calculator's current value. Implement the following methods as listed below: Default constructor method to set the attribute to 0.0 add(self, val) - add the parameter to the attribute subtract(self, val)- subtract the parameter from the attribute multiply(self, val) - multiply the attribute by the parameter divide(self, val)- divide the attribute by the parameter clear(self) - set the attribute to 0.0 get_value(self) - return the attribute Given two float input values num1 and num2, the program outputs the following values: The initial value of the instance attribute, value The value after adding num1 The value after multiplying by 3 The value after subtracting num2 The value after dividing by 2 The value after calling the clear() method

23.2 LAB: Calculator class (Use Python)
In the file main.py write a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one attribute called value for the calculator's current value. Implement the following methods as listed below:
- Default constructor method to set the attribute to 0.0
- add(self, val) - add the parameter to the attribute
- subtract(self, val)- subtract the parameter from the attribute
- multiply(self, val) - multiply the attribute by the parameter
- divide(self, val)- divide the attribute by the parameter
- clear(self) - set the attribute to 0.0
- get_value(self) - return the attribute
Given two float input values num1 and num2, the program outputs the following values:
- The initial value of the instance attribute, value
- The value after adding num1
- The value after multiplying by 3
- The value after subtracting num2
- The value after dividing by 2
- The value after calling the clear() method
Ex: If the input is:
10.0
5.0
the output is:
0.0
10.0
30.0
25.0
12.5
0.0
