Classes

Hotel Class

The Hotel class represents a hotel with several attributes and methods.

class Hotel:
    sortParam='name'
    def __init__(self) -> None:
        self.name = ''
        self.roomAvl = 0
        self.location = ''
        self.rating = int
        self.pricePr = 0

• Attributes:

  • name: The name of the hotel.
  • roomAvl: The number of available rooms.
  • location: The location of the hotel.
  • rating: The rating of the hotel.
  • pricePr: The price per room.

• Class Attribute:

  • sortParam: A class-level attribute that determines the sorting parameter (default is 'name').

The __init__ method initializes these attributes with default values.

    def __lt__(self, other):
        return getattr(self, Hotel.sortParam) < getattr(other, Hotel.sortParam)

• __lt__ Method:
  • This is a special method used to define the behavior of the less-than operator < for Hotel objects. It uses the current sorting parameter (sortParam) to compare two Hotel instances.

    @classmethod
    def sortByName(cls):
        cls.sortParam = 'name'

    @classmethod
    def sortByRate(cls):
        cls.sortParam = 'rating'

    @classmethod
    def sortByRoomAvailable(cls):
        cls.sortParam = 'roomAvl'

• Class Methods:
  • sortByName: Sets sortParam to 'name'.
  • sortByRate: Sets sortParam to 'rating'.
  • sortByRoomAvailable: Sets sortParam to 'roomAvl'.

These class methods allow changing the sorting parameter at the class level.

    def __repr__(self) -> str:
        return "PRHOTELS DATA:\nHotelName:{}\tRoom Available:{}\tLocation:{}\tRating:{}\tPricePer Room:{}".format(self.name, self.roomAvl, self.location, self.rating, self.pricePr)

• __repr__ Method:
  • Provides a string representation of the Hotel object, which is useful for printing the object in a readable format.

User Class

The User class represents a user with several attributes.

class User:
    def __init__(self) -> None:
        self.uname = ''
        self.uId = 0
        self.cost = 0

• Attributes:
  • uname: The username.
  • uId: The user ID.
  • cost: The booking cost.

    def __repr__(self) -> str:
        return "UserName:{}\tUserId:{}\tBooking Cost:{}".format(self.uname, self.uId, self.cost)

• __repr__ Method:
  • Provides a string representation of the User object, useful for printing.
