質問 # 50
Select the true statement about the socket. gaierror exception.

A. It is raised when a timeout occurs on a socket.
B. It is raised when an address-related error caused by the getaddrinfo () and getnameinfo () functions occurs.
C. It is raised when a system function returns a system-related error.
D. It is raised when an address-related error caused by the repr () function occurs.

正解：B

解説：
Explanation
The socket.gaierror exception is raised when an address-related error caused by the getaddrinfo() and getnameinfo() functions occurs. These functions are used to translate hostnames to IP addresses and vice versa, and the gaierror exception is raised if they fail to perform this translation.

質問 # 51
Which sentence about the property decorator is false?

A. The property decorator should be defined after the method that is responsible for setting an encapsulated attribute.
B. The property decorator should be defined before the methods that are responsible for setting and deleting an encapsulated attribute
C. The @property decorator designates a method which is responsible for returning an attribute value
D. The property decorator marks the method whose name will be used as the name of the instance attribute

正解：A

解説：
The @property decorator should be defined after the method that is responsible for setting an encapsulated attribute is a false sentence. In fact, the @property decorator should be defined before the method that is used to set the attribute value. The @property decorator and the setter and deleter methods work together to create an encapsulated attribute, which is used to provide control over the attribute's value.
Reference:
Official Python documentation on Property: https://docs.python.org/3/library/functions.html#property The @property decorator is used to designate a method as a getter for an instance attribute. The method decorated with @property should be defined before any setter or deleter methods for the same attribute.

質問 # 52
Analyze the following snippet and decide whether the code is correct and/or which method should be distinguished as a class method.

A. The code is erroneous.
B. The getNumberofCrosswords () method should be decorated With @classmethod.
C. The gexNumberOfcrosswords () and issrived methods should be decorated with @classzoechod.
D. There is only one initializer, so there is no need for a class method.

正解：B

解説：
Explanation
The correct answer is B. The getNumberofCrosswords() method should be decorated with @classmethod. In the given code snippet, the getNumberofCrosswords method is intended to be a class method that returns the value of the numberofcrosswords class variable. However, the method is not decorated with the @classmethod decorator and does not take a cls parameter representing the class itself. To make getNumberofCrosswords a proper class method, it should be decorated with @classmethod and take a cls parameter as its first argument.
The getNumberofCrosswords() method should be decorated with @classmethod.
This is because the getNumberofCrosswords() method is intended to access the class-level variable numberofcrosswords, but it is defined as an instance method, which requires an instance of the class to be created before it can be called. To make it work as a class-level method, you can define it as a class method by adding the @classmethod decorator to the function.
Here's an example of how to define getNumberofCrosswords() as a class method:
classCrossword:
numberofcrosswords =0
def __init__(self, author, title):
self.author = author
self.title = title
Crossword.numberofcrosswords +=1
@classmethod
defgetNumberofCrosswords(cls):
returncls.numberofcrosswords
In this example, getNumberofCrosswords() is defined as a class method using the @classmethod decorator, and the cls parameter is used to access the class-level variable numberofcrosswords.

質問 # 53
Look at the following examples of comments and docstrings in PythonSelect the ones that are useful and compliant with PEP 8 recommendations (Select the two best answers.) A)

正解：A、D

解説：
Explanation
According to PEP 8 recommendations, the two best options are Option B and Option D.
Option B follows PEP 8's suggestion that all lines should be limited to 79 characters and for longer blocks of text like docstrings or comments, the length should be limited to 72 characters1. Option D follows PEP 8's conventions for writing good documentation strings (a.k.a. "docstrings") which are immortalized in PEP
257. It suggests writing docstrings for all public modules, functions, classes, and methods2.
