class Calculator:

    # Type your code here.

if __name__ == "__main__":

    calc = Calculator();
    num1 = float(input())
    num2 = float(input())

    # 1. The initial value
    print('{:.1f}'.format(calc.get_value()))

    # 2. The The value after adding num1
    calc.add(num1)
    print('{:.1f}'.format(calc.get_value()))

    # 3. The value after multiplying by 3
    calc.multiply(3)
    print('{:.1f}'.format(calc.get_value()))

    # 4. The value after subtracting num2
    calc.subtract(num2)
    print('{:.1f}'.format(calc.get_value()))

    # 5. The value after dividing by 2
    calc.divide(2)
    print('{:.1f}'.format(calc.get_value()))

    # 6. The value after calling the clear() method
    calc.clear()
    print('{:.1f}'.format(calc.get_value()))

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: 1. The initial value of the instance attribute, value 2. The value after adding num1 3. The value after multiplying by 3 4. The value after subtracting num2 5. The value after dividing by 2 6. 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
