PyTest - Writing Assertions

Consider this pytest test:

def test_identity():
    a = [1, 2]
    b = a.copy()
    assert a is not b
    assert a == b

What is the purpose of these assertions?

ATo check that <code>a</code> and <code>b</code> are different objects but have equal values

BTo check that <code>a</code> and <code>b</code> are the same object and have equal values

CTo check that <code>a</code> and <code>b</code> are different objects and different values

DTo check that <code>a</code> and <code>b</code> are the same object but different values

Step-by-Step Solution

Solution:

Step 1: Understand copy() behavior
b = a.copy() creates a new list object with the same values as a.
Step 2: Analyze assertions
assert a is not b confirms different objects; assert a == b confirms equal values.
Final Answer:
To check that a and b are different objects but have equal values -> Option A
Quick Check:
Copy creates equal but distinct objects = B [OK]

Quick Trick: copy() creates equal but distinct objects [OK]
