Consider this simplified DDD code snippet in Python:

class Order:
    def __init__(self, order_id, items):
        self.order_id = order_id
        self.items = items

order1 = Order(1, ['apple', 'banana'])
order2 = Order(1, ['apple', 'banana'])

print(order1 == order2)

What will be the output?

ATrue

BFalse

CSyntaxError

DNone

Step-by-Step Solution

Solution:

Step 1: Understand default equality in Python classes
By default, Python compares object references, so two different instances with same data are not equal.
Step 2: Analyze the code output
order1 and order2 are different objects with same data, so order1 == order2 returns False.
Final Answer:
False -> Option B
Quick Check:
Default object equality compares references = False [OK]

Quick Trick: Default == compares object identity, not data [OK]

Common Mistakes:

Assuming == compares data automatically
Expecting True because attributes match
Confusing syntax error with logic error
