To do so, define a function calculate() with a three parameters:\ \ operation | The value specified for the operation parameter on execution will indicate which operation to perform\ num1 | The first value to be used in the calculation\ num2 | The second value to be used in the calculation\ The calculator will assign the output of its calculation to a variable called answer, which will be returned from the function.\ \ Specifically, create the calculate() function such that:\ \ if operation has the value 'add', then answer gets set as the sum of num1 and num2\ elif operation has the value 'subtract', then answer gets set as the difference of num2 from num1\ elif operation has the value 'multiply', then answer gets set as the product of num1 and num2\ elif operation has the value 'divide', then answer gets set as the quotient of num1 divided by num2\ else answer gets set as the value 'not a thing'\ For an example, if we were to execute our function as follows:\ \ output = calculate(operation='multiply', num1=2, num2=3)\ we would expect output to store 6.
