Python - Constructors and Object Initialization

How can you modify this constructor to accept a list of hobbies and store a copy to avoid external changes?

class User:
    def __init__(self, name, hobbies):
        self.name = name
        self.hobbies = hobbies

Aself.hobbies = hobbies.append([])

Bself.hobbies = hobbies

Cself.hobbies = hobbies.copy()

Dself.hobbies = hobbies.extend([])

Step-by-Step Solution

Solution:

Step 1: Understand shared mutable references
Assigning hobbies directly links to the original list, so changes outside affect the object.
Step 2: Use copy to avoid shared references
Using hobbies.copy() creates a new list, protecting the object's data.
Final Answer:
self.hobbies = hobbies.copy() -> Option C
