You are correct that the hasattr() function is not a method. In Python, methods are functions that are defined inside a class and are associated with objects of that class, while functions are standalone blocks of code that are not associated with any particular class or object. However, the hasattr() function can still be used to safely check for the presence of an attribute on an object, even though it is not a method. To use the hasattr() function, you simply pass the object as the first argument and the name of the attribute as the second argument

Correct answer is C, information from Python course, singned by Python Institute: Python provides a function which is able to safely check if any object/class contains a specified property. The function is named hasattr, and expects two arguments to be passed to it: the class or the object being checked; the name of the property whose existence has to be reported (note: it has to be a string containing the attribute name, not the name alone)

The answers in the dumps are good to remember! The bulk of the exam questions are from these exam dumps. The questions with mistakes in them or missing : etc are in the exam but in the correct answer form, do remember the correct answers as well as the answers with the mistakes in the coding. There are a few questions that are slightly different but you can find the answers from the previous or next question/answers! Hope this helps!

Option B: Correct because hasattr() is indeed a method (function) provided by Python to check if an object has a certain attribute. Option C: Incorrect because it has a typo. The correct function is hasattr(), not hassattr().

Correct answer is C: hasattr() is a function not a method. the extra 's' on option C could be a typo error. =====> Using hasattr() function: The hasattr() function can be used to determine if an object or class has a specific attribute. It takes two arguments: the object or class to check, and the name of the attribute as a string. It returns True if the attribute exists and False otherwise

Selected Answer: A
The answer is A. It does not ask what hasattr is but if you can safely check for an attribute in a class. So if you use hasattr function and the attribute you can find it.
