Code :
a = 10
b = 10
print(f"a is b: {a is b}")
print(f"a == b: {a == b}")
Answer :
Solution and Explanation:
the code line by line:
a = 10
Here, you are assigning the value 10 to the variable a. This means that the variable a now refers to the integer object 10.
b = 10
Similarly, you are assigning the value 10 to the variable b. Like before, the variable b now refers to the same integer object 10. In Python, for small integers, the interpreter often optimizes and reuses the same object in memory.
print(f"a is b: {a is b}")
This line prints the result of the identity comparison using the is operator. It checks if the variables a and b refer to the exact same object in memory. Since integers are often optimized for small values, a is b will usually be True because both variables reference the same 10 object in memory.
print(f"a == b: {a == b}")
This line prints the result of the equality comparison using the == operator. It checks if the values of a and b are equal. Since both a and b have the value 10, a == b will be True.
In summary, the code demonstrates the difference between the is operator, which checks identity (whether two variables reference the exact same object), and the == operator, which checks equality (whether the values of two variables are the same). In this specific case with small integers, both comparisons evaluate to True.
