Python - Constructors and Object Initialization

You want to create a class Book that stores title and author. Which constructor correctly initializes these attributes and allows creating a Book object with both values?

Adef __init__(self, author): self.title = title self.author = author

Bdef __init__(self, title, author): self.title = title self.author = author

Cdef __init__(self, title): self.title = title self.author = author

Ddef __init__(self): title = '' author = ''

Step-by-Step Solution

Solution:

Step 1: Check parameters needed
Both title and author must be passed to the constructor to initialize attributes.
Step 2: Verify attribute assignment
Constructor must assign both self.title and self.author from parameters.
Final Answer:
def __init__(self, title, author): self.title = title self.author = author -> Option B
Quick Check:
Constructor with all attributes assigned = def __init__(self, title, author): self.title = title self.author = author [OK]

Quick Trick: Constructor needs all attributes as parameters and assigns them [OK]

Common Mistakes:

Missing parameters for all attributes
Assigning attributes without parameters
Using local variables instead of self attributes
