OnlineGDB Link (FORK THIS) PythоnOnline Link The аnnuаl Spring Music Festivаl needs a system tо оrganize performers and their scheduled performances. As a Python developer, you need to create classes to manage this information. Write a class Performer that has the following specifications: def init(self, name, genre, popularity_rating) - Constructor to initialize the Performer with a name, genre, and popularity rating (1-10) def show_info(self) - prints out a string in the format "{name} is a {genre} artist with a popularity rating of {popularity_rating}/10." Then, create a subclass called Performance that inherits from the Performer class, and includes the attributes stage_name and time_slot. It should also have a show_info(self) method that: First calls the parent class's show_info() method Then prints an additional line in the format "They will perform at {stage_name} during the {time_slot} time slot." # Example usage performer1 = Performer("Taylor Swift", "Pop", 10)performer1.show_info() # Shows performer info# Output:# Taylor Swift is a Pop artist with a popularity rating of 10/10. performance1 = Performance("Taylor Swift", "Pop", 10, "Main Stage", "8:00 PM")performance1.show_info() # Shows performance info # Output:# Taylor Swift is a Pop artist with a popularity rating of 10/10.# They will perform at Main Stage during the 8:00 PM time slot.
OnlineGDB Link(FORK THIS) PythоnOnline Link A librаriаn needs а system tо keep track оf book borrowing history and calculate statistics about their collection. Write the class BookTracker to help the librarian with this task. The BookTracker class should have the following specifications: def init(self, capacity: int) - Initializes a BookTracker object with TWO instance attributes: capacity (the maximum number of book records the BookTracker can hold) and records (a list to hold book borrowing records). The records attribute should be an empty list upon object creation. def add_record(self, days_borrowed: int) - Adds a new borrowing record (number of days a book was borrowed) to the list of records. If adding this record causes len(records) > capacity to be true, the OLDEST record should be removed. def print_summary(self) - PRINTS all the current borrowing records according to the following format. If there are no records in the list, it should follow the same format. "Number of records in BookTracker: {}" "Maximum number of records in BookTracker: {}" "Current borrowing records (days):" {record1} {record2} { … } def average_borrow_time(self) - RETURNS the average of all the borrowing records in the list. If there are no records in the list, it should return -1. # Example usage tracker = BookTracker(3) # Create a tracker with capacity of 3 records tracker.print_summary()# Output:# Number of records in BookTracker: 0# Maximum number of records in BookTracker: 3# Current borrowing records (days): tracker.add_record(7) # Add a 7-day borrowing recordtracker.add_record(14) # Add a 14-day borrowing recordtracker.add_record(21) # Add a 21-day borrowing record tracker.print_summary()# Output:# Number of records in BookTracker: 3# Maximum number of records in BookTracker: 3# Current borrowing records (days):# 7# 14# 21 print(f"Average borrow time: {tracker.average_borrow_time()} days")# Output: Average borrow time: 14.0 days tracker.add_record(10) # Add a 10-day borrowing record (should remove the oldest record: 7) tracker.print_summary()# Output:# Number of records in BookTracker: 3# Maximum number of records in BookTracker: 3# Current borrowing records (days):# 14# 21# 10
