Question
How many objects and reference variables are there for the given Python code?
class A:
print("Inside class")
A()
A()
obj = A()
2 and 13 and 33 and 13 and 2
Solution
The given Python code is:
class A:
print("Inside class")
A()
A()
obj=A()
2 and 13 and 33 and 13 and 2
Let's break it down:
-
class A:
- This line defines a class namedA
. No objects or reference variables are created here. -
print("Inside class")
- This line is inside the class definition. It doesn't create any objects or reference variables. -
A()
- This line creates an instance of classA
, which is an object. However, this object is not assigned to any reference variable, so it's not accessible after this line. This happens twice in the code, so 2 objects are created here. -
obj=A()
- This line also creates an instance of classA
, which is another object. This object is assigned to the reference variableobj
, so it's accessible later in the code. So, 1 object and 1 reference variable are created here. -
2 and 13 and 33 and 13 and 2
- This line doesn't create any objects or reference variables. It's a logical AND operation on integers, which results in the last value (2 in this case) if all values are truthy (non-zero), and doesn't create any new objects or reference variables.
So, in total, the given Python code creates 3 objects and 1 reference variable.
