Exam PCPP-32-101 Topic 2 Question 38 Discussion

Actual exam question for Python Institute's PCPP-32-101 exam
Question #: 38
Topic #: 2
Which function or operator should you use to obtain the answer True or False to the question: "Do two variables refer to the same object?"

Suggested Answer: D Vote an answer

Explanation
To test whether two variables refer to the same object in memory, you should use the is operator.
The is operator returns True if the two variables point to the same object in memory, and False otherwise.
For example:
a = [1, 2, 3]
b = a
c = [1, 2, 3]
print(a is b) # True
print(a is c) # False
In this example, a and b refer to the same list object in memory, so a is b returns True. On the other hand, a and c refer to two separate list objects with the same values, so a is c returns False.
