OnlineGDB Link(FORK THIS) PythоnOnline Link A lоcаl hоtel hаs а program to keep track of who is staying in their hotel. In that program is the GuestBook class. The GuestBook class tracks the names of all guests that are currently in the hotel. The hotel has tasked you with writing a new class, NewGuestBook, that inherits from the GuestBook class and counts the total number of guests that have stayed at the hotel. You may not modify the original GuestBook class, but you may add whatever methods you would like to the NewGuestBook. The GuestBook class has the following methods: def __init__(self) - Initializes an empty GuestBook. def check_in(self, name) - Adds name to the GuestBook. def check_out(self, name) - Removes a name from the GuestBook. def get_names(self) - Returns the names of all the guests currently in the hotel. Your NewGuestBook class must add the following method: def get_count(self) - Returns the total number of guests that have stayed at the hotel. # Example usage book = NewGuestBook()book.check_in("Will")book.check_in("Billy Bob")book.check_out("Will")book.check_in("John")book.check_in("Eric")book.check_out("Billy Bob")book.check_out("John")print(book.get_count(), "guests have stayed in the hotel") # Output 4 guests have stayed in the hotel
