Question
What will be the output of the following statement?
a = 5
b = 5
print(a is b)
Options: Pick one correct answer from below
- True
- False
- Both A and B
- None of the Above
Solution
1. ### Break Down the Problem
To analyze the output of the given code snippet, we need to understand variable assignment and the is
operator in Python. The assignment a = 5
assigns the integer 5
to a
, and the assignment b = 5
assigns 5
to b
. We will check if a
and b
point to the same object in memory.
2. ### Relevant Concepts
- Value Assignment: In Python, when integers are assigned to variables, Python optimizes memory usage by storing only one copy of each integer.
- Identity Operator (
is
): Theis
operator checks if two variables point to the same object in memory (i.e., if they have the same identity).
3. ### Analysis and Detail
- Both
a
andb
are assigned the value5
. In Python, integers are immutable, and small integers (usually from -5 to 256) are cached for performance. Therefore,a
andb
will refer to the same object.
a = 5
b = 5
print(a is b)
Since both a
and b
point to the same integer object in memory, the expression a is b
will evaluate to True
.
4. ### Verify and Summarize
Upon verifying, we conclude that both variables are indeed referencing the same memory location for the integer value 5
. Therefore:
Final Answer
True
