OnlineGDB: LINK A music festivаl needs а system tо mаnage different types оf musicians. Yоu are tasked with designing classes using inheritance to manage this information. Musician (parent class): def __init__(self, name: str, genre: str, experience: int) - Constructor to initialize the Musician with a name, genre, and years of experience. def perform(self) - RETURNS a string in the format "{name} performs!" def get_info(self) - RETURNS a string in the format "{name} - {genre} ({experience} years of experience)" Guitarist (inherits from Musician): def __init__(self, name: str, genre: str, experience: int, guitar_type: str) - A constructor that initializes all musician attributes, plus guitar type. def perform(self) - RETURNS a string in the format "{name} shreds on their {guitar_type}!" def get_info(self) - RETURNS a string containing the parent class info on the first line, followed by "Guitar: {guitar_type}" on the second line. Vocalist (inherits from Musician): def __init__(self, name: str, genre: str, experience: int, vocal_range: str) - A constructor that initializes all musician attributes plus vocal range. def perform(self) - RETURNS a string in the format "{name} sings in a {vocal_range} voice!" def get_info(self) - RETURNS a string containing the parent class info on the first line, followed by "Vocal range: {vocal_range}" on the second line. Example Usage: guitarist = Guitarist("Jimi", "Rock", 10, "Fender Stratocaster")print(guitarist.get_info())print(guitarist.perform())# Output:# Jimi - Rock (10 years of experience)# Guitar: Fender Stratocaster# Jimi shreds on their Fender Stratocaster!vocalist = Vocalist("Aria", "Jazz", 7, "soprano")print(vocalist.get_info())print(vocalist.perform())# Output:# Aria - Jazz (7 years of experience)# Vocal range: soprano# Aria sings in a soprano voice!
