Exam PCAP topic 1 question 73 discussion

serious capitalization typos, however the correct answer is B. class X: pass class Y(X): pass class Z(Y): pass x = Z() z = Z() print(isinstance (x, Z), isinstance (z, X)) >>>True True

Should be B

B True True. In this code: There are three classes: X, Y, and Z. Class Y inherits from class X, and class Z inherits from class Y. Two instances, x and z, are created as objects of class Z. The isinstance function is then used to check the types of these instances. Here's the breakdown: x = Z(): This line creates an instance of class Z and assigns it to the variable x. z = Z(): This line creates another instance of class Z and assigns it to the variable z. Now, let's look at the print statement: print(isinstance(x, Z), isinstance(z, X)): This line checks if x is an instance of Z (which it is, as x was instantiated from class Z). It also checks if z is an instance of X (which it is, as Z inherits from Y and Y inherits from X). So, the output of this code will be: B True True.

Answer is B....if it wasn't for the typos.

Should be B

The answer is B

B. True True

I try to focus on x, X, z, Z. There is no any correct answer.

True True

If you do: class X: pass class Y(X): pass class Z(Y): pass x = Z() z = Z() print(isinstance(x,Z), isinstance(z,X)) >> True True So B is the answer

True True indeed, tested it and that's the result when all typos are corrected. B is correct

Please fix these typo's.

Should be NameError: name 'x' is not defined.

Correct answer is B. True True
