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:

  1. class A: - This line defines a class named A. No objects or reference variables are created here.

  2. print("Inside class") - This line is inside the class definition. It doesn't create any objects or reference variables.

  3. A() - This line creates an instance of class A, 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.

  4. obj=A() - This line also creates an instance of class A, which is another object. This object is assigned to the reference variable obj, so it's accessible later in the code. So, 1 object and 1 reference variable are created here.

  5. 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.
