Object = Upper() creates an instance of the Upper class.
isinstance(Object, Lower) evaluates to False because Object is an Upper instance, not a Lower instance or its subclass.
The end=' ' keeps the output on one line
Object.method() calls the method from the Upper class.
This results in the combined output: False upper.
Explanation:
Step-by-Step Breakdown:
Class Definitions:
Upper: Defines a method that returns the string ‘upper'.
Lower: Inherits from Upper and overrides the method to return the string ‘lower'.
Creating an Object:
Object = Upper() creates an instance of the Upper class.
Object is an instance of Upper, not Lower.
isinstance(Object, Lower):
The isinstance function checks if Object is an instance of the Lower class or any of its subclasses.Since Object is explicitly an instance of Upper, and Upper is not a subclass of Lower, this evaluates to False.
Object.method(): Object.method() calls the method defined in the Upper class because Object is an instance of Upper. This method returns ‘upper'.
print Statement: The first part of the print statement outputs False (from isinstance). The second part outputs upper (from Object.method()). The end=' ' ensures the two outputs are on the same line, separated by a space.
The correct answer is: B. False upper
