PyTest - Writing Assertions

What will be the result of this pytest assertion?

list1 = [1, 2, 3]
list2 = list1
assert list1 is list2

ASyntax error due to incorrect assertion

BThe assertion fails because the lists have the same values but are different objects

CThe assertion passes because both variables refer to the same list object

DRuntime error because lists cannot be compared with 'is'

Step-by-Step Solution

Solution:

Step 1: Analyze variable assignment
Both list1 and list2 point to the same list object because list2 = list1 assigns the reference.
Step 2: Understand the assertion
assert list1 is list2 checks identity, which is true here.
Final Answer:
The assertion passes because both variables refer to the same list object -> Option C
Quick Check:
Identity assertion passes = A [OK]

Quick Trick: Assigning one variable to another shares the same object [OK]
