Python - Constructors and Object Initialization

What will be the output of this code?

class Book:
    def __init__(self, title, pages=100):
        self.title = title
        self.pages = pages

book1 = Book('Python 101', 250)
book2 = Book('Learn AI')
print(book1.pages, book2.pages)

A100 250

B250 100

C250 250

DError: Missing argument for title

Step-by-Step Solution

Solution:

Step 1: Understand argument passing
book1 passes both title and pages, so pages=250. book2 passes only title, so pages uses default 100.
Step 2: Print pages attributes
book1.pages is 250, book2.pages is 100, so output is '250 100'.
Final Answer:
250 100 -> Option B
Quick Check:
Explicit args override defaults [OK]

Quick Trick: Explicit argument replaces default value [OK]

Common Mistakes:

Mixing order of arguments
Assuming default always used
Expecting error without all arguments
