Question
In the following code, do a
and b
point to the same object?
Answer with Yes or No.
>>> a = 89
>>> b = a
Solution
Final Answer
No.
Explanation
In Python, when you assign a variable like b = a
, you are not creating a new object; instead, you're making b
refer to the same object that a
is pointing to. However, the key point here is that integer objects in Python are immutable. This means that when you perform an operation that changes the value, like a = a + 1
, a
would then point to a new integer object, while b
would still point to the original integer object (89 in this case).
In your example, a
is assigned an integer value of 89 and then b
is set to reference a
. At that moment, both a
and b
refer to the same integer object. However, if either variable changes to point to a different integer, they will then point to different objects. Thus, after this specific code execution, a
and b
do initially point to the same object. However, Python's behavior regarding mutability and reference counting is crucial for understanding object references in coding.
