Question 10

Create a class ParkedVehicle with below attributes:

vehicleSeq –Integer type

fourWheeler – String type

parkedFor – float type

valetParking – String type

parkedStatus – String type

vehicleSeq represents a unique identification number for each of the parked vehicle

fourWheeler represents if the vehicle is a four wheeler or Not (“Yes“ / “No“ are the possible values)

parkedFor represents the number of hours for which the vehicle was parked

valetParking – if the vehicle is parked using valet parking (“Yes“ / “No“ are the possible values)

parkedStatus represents if the vehicle is “Parked“ or “Cleared“

Define the __init__ method to initialize all the attributes (mentioned above, in the sequence ) except parkedStatus. The parkedStatus will be set as default argument with a value “Parked” in the constructor during the respective object creation.

The constructor will be called from main function. The input data read in the main function and supplied to constructor as mentioned in the above line and in the sequence mentioned.

Create a class ParkingLot with below attributes:

parkd_vehicles – is of type dictionary with ParkedVehicle objects [parking lot_number ( an integer ) and the respective ParkedVehicle object as a key : value pair ]

Define the __init__ method to initialize the dictionary attribute in the class

It initializes the dictionary (parkd_vehicles) of ParkedVehicle objects in the ParkingLot class with the dictionary supplied from main program, while creating the ParkingLot object.

Note: The dictionary is created and filled in main program by adding each ParkedVehicle object(which is created with the input data related to the respective ParkedVehicle )and

passed as an argument to the constructor of ParkingLot class and this will be initialized to parkd_vehicles dictionary attribute of the ParkingLot class

Define two methods – updateParkedStatus and getParkingCharges in ParkingLot class.

Method 1: updateParkedStatus:

This method takes one parameter “lot_number“ , which represents the lot number in which the respective vehicle is parked(ParkedVehicle object) and update the “parkedStatus“ attribute of the respective ParkedVehicle object ( in the parkd_vehicles dictionary in ParkedLot class ) to ‘Cleared’.

This method makes use of the parkd_vehicles (dictionary of ParkedVehicle objects) in the ParkingLot class to find the ParkedVehicle in the given lot number and updates the parkedStatus to “Cleared”.

The method should return a tuple where key is the given lot_number (supplied as parameter ) and the value is the updated parkedStatus of the respective ParkedVehicle object, which is “Cleared” .

Ex:- (56, ParkedVehicle_obj.parkedStatus)

Display the Lot number and status (returned by this function) in the main function. Refer the sample output for display format

If the given lot number is not found in the “parkd_vehicles“ dictionary attribute, return None to the main function and accordingly display “Lot Number Invalid” in main function.

Method2: getParkingCharges:

This method will take lot_number as parameter and return the parking charges of the ParkedVehicle object associated with the lot number given. (use the “parkd_vehicles“ attribute in the ParkingLot class). Refer Parking charges calculation below.

If the given lot number is found then calcute the parking charges and return to main function. Display the parking charges returned by this function in the main function. Refer the sample output for display format .

If the given lot number is not found in the “parkd_vehicles“ dictionary attribute, return None to the main function and accordingly display “Lot Number Invalid” in main function.

Important instruction:

Use the same lot number (which is supplied as a parameter to updateParkedStatus function) as a parameter to this function as well.

Parking Charges rules and calculation:

a.Parking is charged on an hourly basis.

b.For a four wheeler, then charge Rs 50 per hour and if the vehicle is not a four wheeler then charge Rs 30 per hour.

c. If valetParking service is used then Rs10 is added to the total parking charges.

d. parkedFor attribute of the respective ParkedVehicle object represents the number of parking hours of the respective parked vehicle.

Case1: if fourWheeler attribute value of the respective ParkedVehicle object is “Yes“ then the parking charges calculated as below;

Parking charges = Charge per hour for four wheeler * ParkedVehicle_obj.parkedFor

Ex: If four wheeler is parked for 5 hours , the parking charge = 50.0 * 5=250.0

If valetParking attribute for the respective ParkedVehicle object is “Yes“ then add Rs10 to the parking charges ie 250.0+10=260.0

Case2: if fourWheeler attribute value of the respective ParkedVehicle object is “No“ then the parking charges are calculated as below:

Parking charges =Charge per hour for Non four wheeler * ParkedVehicle_obj.parkedFor

Ex: If Non four wheeler is parked for 3 hours ; the charges are = 30.0 * 3= 90.0

If valetParking attribute for the respective ParkedVehicle object is “Yes“ then add Rs10 to the parking charges ie 90.0+10=100.0

The two methods should be called from the main function / program in the same sequence as above

Use the dictionary parkd_vehicles in ParkingLot object to find out the parked vehicle object for a given lot number[ by comparing the lot number given with the lot number in the parkd_vehicles].

Instructions to write main and to call the methods of the classes defined above:

a. You would required to write the main program completely, Please follow the below instructions for the same.

b. You would required to write the main program which is inlign to the sample input data section mentioned below and to read the same

c. Create the respective objects(ParkedVehicle and ParkingLot) with the given sequence of arguments to fulfill the constructor requirement defined in the respective classes.

i.Create a ParkedVehicle object after reading the data related to ParkedVehicle and add the ParkedVehicle object to ParkedVehicle dictionary,

where lot_number and Parked vehicle object as a key:value pair. This point repeats for the number of ParkedVechicle objects you want to create and add to parked vehicles dictionary.

ii. Create parkingLot object with the dictionary of ParkedVehicle objects ( created as mentioned in above point# c.i ), as an argument.

d. Call the methods ( updateParkedStatus and getParkingCharges ) mentioned above from the main function in the same order , they appear in the question text.

e. Display the data returned by the functions , in the main program as per the format mentioned in the sample output.

f. If None is returned by any or both of the above functions, indicating that the given lot number does not exists , then display the message “Lot Number Invalid”(excluding the double quotes) in the main function.

Question 11:Online Vegetable Store

​Create a class Vegetable with the below attributes:

name of type String name of the vegetable price of type float //price ( in Rupees ) of the Fx: Kilogram quantity of type int ,/ quantity — number of units / Number of Kilograms

​Create the init method which takes all parameters in the above sequence. The method should set the value of attributes with the parameter values received from main function.

Create another class Store with the below attribute: storeName of type String /specifies the vegList of type List L ist of Vegetable which takes all sequence. The method should set the value of attributes with the parameter values received from main.

​Create method inside the Store class with name categorizeVegetablesAlphabetically

This method use and traverse the list of Vegetables(vegList) and returns a dictionary of alphabetically categorized and sorted vegetable names(name), where in key represent an alphabet character(e.g. ‘a’, ‘b’, se etc) and value represents a tuple, containing vegetable names that starts with that specific character as per key. Both the keys and values are sorted in alphabetically. The comparison needs to be case insensitive. If there are more vegetable names starts with the respective alphabet (which is acting as the key for the respective tuple of vegetable names), then the list of vegitable names also needs to be sorted.
e.g. Ex on fruits, resultant dictionary data looks like : fas:(‘ananas’, ‘apple), ’13: (‘banana’), ‘p’:(‘pineapple)) Here ‘a’ ,’b’ and ‘p’ (excluding the single quote ) represents the keys of dictionary and (‘ananass, ‘apple), (‘banana’), (pineapple’) ,excluding the ‘single quote and brackets’ represents the tuple for respective and corresponding keys(a , b, p ).

​For more details refer the sample test case input and respective output

Create another method inside Store class with the name filterVegetablesForPriceRange This method takes minimum price and maximum price in Rupees as input parameters and return a list of alphabetically sorted vegetable names(name), where in the Vegetable unit price falls in the given range(minimum price and maximum price). This method use and traverse the list of Vegetables(vegList) for comparing the price of vegetable per Unit with the given range

If there is no vegetable in given price range, the method returns an empty list and based on the value main function should print “No Vegetable(s) in the given price range” (Excluding the double quotes) .

Question 12:Create a class FoodItem with the below attributes:

item_id of type Number
item_name of type String
item_category of type String
item_price of type Number

​Create the init method which takes all parameters in the above sequence. The method should set the value of attributes to parameter values.

Create a method inside the class with the name provideDiscount. This method takes a Number value as argument which is the percentage by which the item price should be discounted and discounts the item price of the food item by the given percentage amount. Returns the updated price of the given item.
e.g. If the food item price is 100 and the given percentage is 10, then the updated price of the food item should be 90.Create another class Restaurant with the below attributes:
restaurant_name of type String
fooditem_list of type List having Foodltem objects

Create the init method which takes all parameters in the above sequence. The method should set the value of attributes to parameter values inside the method.

Create another method inside the class with the name retrieveUpdatedPrice. The method takes the update percentage as first argument and item id as the second argument . The method should find the respective food item, whose item id is given as in the argument , discount the price as per the given percentage and return the respective Foodltem object.

​If the food item with given item id is not found , then the method returns None . Note: In Python None means NULL Object , Accordingly default maiN will display the message ‘No Food item exists which matches the search criteria’ (excluding the quotes)
If the update discount percent (argument to this function) is less than equals to zero , then return the object as it is , means there would not be any changes to the price.
Note: Use the method provideDiscount defined in the Foodltem class to calculate the discount price of the food items .

Instructions to write the main section of the code:
a. You would require to write the main section completely, hence please follow the below instructions for the same.
b. You would require to write the main program which is inline to the “sample input description section” mentioned below and to read the data in the same sequence.
c. Create the respective objects(Foodltem and Restaurant) with the given sequence of arguments to fulfill the Unit_ method requirement defined in the respective classes referring to the below instructions. i. Create a Foodltem object after reading the data related to it and add the object to the list of Foodltem objects which will be provided to the Restaurant class.This point repeats for the number of Foodltem objects(considered in the first line of input) . ii. Create Restaurant object by passing the Restaurant name(you can hard-code any name you want)and List of Foodltem objects ( created and as mentioned in above point# c.i ) as the arguments.
d. Take two number values as input depicting the item_id and the discount percentage to be provided as arguments to the method retrieveUpdatedPrice. e. Call the method retrieveUpdatedPrice mentioned above from the main section.
e. Display the Item Name and the Item Price separated by a ‘-‘ from the returned Foodltem object. Please refer to the sample output for more clarity on the display format.
f. If None is returned by the method retrieveUpdatedPrice ,then display the message No Food item exists which matches the search criterialexcluding the quotes).

•Input Format For Custom Testing
The 1st input taken in the main section is the number of Foodltem objects to be added to the list of FoodItems.
The next set of inputs are the item id, item name, item category and item price for each food item taken one after other and is repeated for number of objects given in the first line of input
