Design the ParcelKoro class such a way so that the following code provides the expected output. Hint total_fee = (total_weight * 20) + location_charge. Note: For the method calculate fee: if the delivery location is not given, the location_charge will be 50 taka or else 100 taka. Also, while calculating total fee, if the product weight is 0 the total_fee should also be 0. Assume only these 3 ways you can create an object of a class.
