Exam PCAP-31-03 topic 1 question 92 discussion

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

B is the Correct answer, tested in IDE
