Select the true statement about the socket. gaierror exception.
- A. It is raised when an address-related error caused by the repr () function occurs.
- B. It is raised when a system function returns a system-related error.
- C. It is raised when a timeout occurs on a socket.
- D. It is raised when an address-related error caused by the getaddrinfo () and getnameinfo () functions occurs.
正解：D
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 # 34
What does the term deserialization mean? Select the best answer.
- A. It is another name for the data transmission process
- B. It is a process of creating Python objects based on sequences of bytes.
- C. It is a process of converting the structure of an object into a stream of bytes
- D. It is a process of assigning unique identifiers to every newly created Python object
正解：B
解説：
A). Deserialization is the process of converting data that has been serialized or encoded in a specific format, back into its original form as an object or a data structure in memory. In Python, this typically involves creating Python objects based on sequences of bytes that have been serialized using a protocol such as JSON, Pickle, or YAML.
For example, if you have a Python object my_obj and you want to serialize it to a JSON string, you might do something like this:
import json
serialized_obj = json. dumps (my_obj)
To deserialize the JSON string back into a Python object, you would use the json.loads() method:
deserialized_obj = json. loads (serialized_obj)
This would convert the JSON string back into its original Python object form.
Reference:
Official Python Documentation on Serialization: https://docs.python.org/3/library/pickle.html#module-pickle Real Python Tutorial on Serialization and Deserialization in Python: https://realpython.com/python- serialization/ Deserialization is the process of converting a sequence of bytes, such as a file or a network message, into a Python object. This is the opposite of serialization, which is the process of converting a Python object into a sequence of bytes for storage or transmission.
質問 # 35
What is true about the unbind_all () method?
(Select two answers.)
- A. It can be invoked from the main window widget only
- B. It can be invoked from any widget
- C. It is parameterless
- D. It causes all the widgets to disappear
正解：B、C
解説：
The unbind_all() method in Tkinter is used to remove all event bindings from a widget. It is a method of the widget object and can be called on any widget in the Tkinter application. Therefore, option A is the correct answer.
Option B is incorrect because the method can be called on any widget, not just the main window widget.
Option C is correct as unbind_all() does not take any parameters.
Option D is incorrect because the method only removes event bindings and does not cause the widgets to disappear.
So, the correct answers are A and C.

質問 # 36
Select the true statements related to PEP 8 programming recommendations for code writing. (Select two answers:)
- A. You should use the not ... is operator (e.g. if not spam is None:), rather than the is not operator (e.g. if spam is not None:), to increase readability.
- B. You should make object type comparisons using the ismstanceQ method (e.g. if isinstance (obj, int) :) instead of comparing types directly (eg if type(obj) is type(i)).
- C. You should write code in a way that favors the CPython implementation over PyPy, Cython. and Jython.
- D. You should not write string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them
正解：B、D
解説：
The two true statements related to PEP 8 programming recommendations for code writing are Option B and Option D .
Option B is true because PEP 8 recommends making object type comparisons using the isinstance() method instead of comparing types directly 1 .
Option D is true because PEP 8 recommends not writing string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them 1 .
質問 # 37
What is true about the unbind () method? (Select two answers.)
- A. It is invoked from within a widget's object
- B. It needs the event name as an argument
- C. It is invoked from within the events object
- D. It needs a widget's object as an argument
正解：A、B
解説：
Option B is true because the unbind() method is invoked from within a widget's object 1 .
Option D is true because the unbind() method needs the event name as an argument 1 .
The unbind() method in Tkinter is used to remove a binding between an event and a function. It can be invoked from within a widget's object when a binding is no longer needed. The method requires the event name as an argument to remove the binding for that specific event. For example:
button = tk.Button(root, text="Click me")
button.bind(" < Button-1 > ", callback_function) # bind left mouse click event to callback_function button.unbind(" < Button-1 > ") # remove the binding for the left mouse click event
質問 # 38
Select the true statements about the sqlite3 module. (Select two answers.)
- A. The fetchalt method returns None when no rows are available
- B. The fetchone method returns None when no rows are available
- C. The execute method allows you to perform several queries at once
- D. The execute method is provided by the Cursor class
正解：B、D
解説：
Explanation
The execute method is provided by the Cursor class
This statement is true because the execute method is one of the methods of the Cursor class in the sqlite3 module. The Cursor class represents an object that can execute SQL statements and fetch results from a database connection. The execute method takes an SQL query as an argument and executes it against the database. For example, cur = conn.cursor (); cur.execute ("SELECT * FROM table") creates and executes a cursor object that selects all rows from a table.
The fetchone method returns None when no rows are available
This statement is true because the fetchone method is another method of the Cursor class in the sqlite3 module.
The fetchone method fetches the next row of a query result set and returns it as a single tuple or None if no more rows are available. For example, row = cur.fetchone () fetches and returns one row from the cursor object or None if there are no more rows.
質問 # 39
Select the true statements related to PEP 8 naming conventions. (Select two answers.)
- A. Constants should be written in all lower-case letters with words separated by underscores
- B. Function and variable names should be lower-case with words separated by underscores.
- C. Modules should have short names written in CameICase.
- D. You should always use self as the first argument to instance methods, and cls as the first argument to class methods.
正解：A、B
解説：
Option A is true because PEP 8 recommends that function and variable names should be lowercase, with words separated by underscores .
Option D is true because PEP 8 recommends that constants should be written in all capital letters with words separated by underscores .
PEP 8 is the official style guide for Python code. It provides guidelines for how to write readable code that follows consistent naming conventions. The aim of PEP 8 is to improve the readability of Python code and make it easier to understand and maintain.
According to PEP 8, variable and function names should be written in all lower-case letters with words separated by underscores, as stated in A. Constants, which are variables whose value is expected to remain constant throughout the code, should be written in all upper-case letters with words separated by underscores, as stated in D.

- A. The code is fine and the script execution is not interrupted by any exception.
- B. The code is an example of explicitly chained exceptions.
- C. The code is an example of implicitly chained exceptions.
- D. The code is erroneous as the OwnMath class does not inherit from any Exception type class
正解：B
解説：
Explanation
In the given code snippet, an instance of OwnMath exception is raised with an explicitly specified __cause__ attribute that refers to the original exception (ZeroDivisionError). This is an example of explicitly chaining exceptions in Python.

質問 # 43
Which of the following methods allow you to load a configuration using ConfigParser? (Select two answers.)
- A. read
- B. read_dict
- C. read_conf
- D. read_str
正解：A、D
解説：
ConfigParser is a built-in library in Python that allows you to read and write configuration files. The read method is used to read the configuration file which can be in any of the supported file formats, such as INI, YAML, and JSON. The read_dict method is used to read the configuration from a Python dictionary. The read_conf and read_str options are not valid methods in the ConfigParser module.
Therefore, the correct options to load a configuration using ConfigParser are A. read and D. read_string.

質問 # 44
Which methods can be invoked in order to draw a triangle?
(Select two answers.)
- A. create_shape()
- B. create_polygon()
- C. create_line()
- D. create_triangle_shape()
正解：B、C
解説：
The correct answers are B and D. In Tkinter's Canvas widget, there is no built-in method named create_shape() or create_triangle_shape(). A triangle can be drawn either with create_line() by connecting three line segments between three coordinate points, or with create_polygon() by providing three vertices. create_polygon() is the more direct method because a triangle is a polygon with three sides, and Tkinter can render it as a filled or outlined shape. create_line() is also valid when the programmer manually draws the three sides and closes the shape. Therefore, the valid Canvas methods for producing a triangle are create_line() and create_polygon().
質問 # 45
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)
- A.
- B.
- C.
- D.
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.
質問 # 46
Which function or operator should you use to obtain the answer True or False to the question: "Do two variables refer to the same object?"
- A. The isinstanceO function
- B. The = operator
- C. The id () function
- D. The is operator
正解：D
解説：
To test whether two variables refer to the same object in memory, you should use the is operator.
The is operator returns True if the two variables point to the same object in memory, and False otherwise.
For example:
a = [1, 2, 3]
b = a
c = [1, 2, 3]
print(a is b) # True
print(a is c) # False
In this example, a and b refer to the same list object in memory, so a is b returns True . On the other hand, a and c refer to two separate list objects with the same values, so a is c returns False .
Reference:
Official Python documentation on Comparisons: https://docs.python.org/3/reference/expressions.html#not-in Official Python documentation on Identity comparisons: https://docs.python.org/3/reference/expressions.
html#is
The is operator is used to test whether two variables refer to the same object in memory. If two variables x and y refer to the same object, the expression x is y will evaluate to True . Otherwise, it will evaluate to False .
質問 # 47
Select the true statement related to PEP 257.
- A. String literals that occur immediately after another docstring are called attribute docstrings.
- B. String literals that occur immediately after a simple assignment at the top level of a module are called complementary docstrings
- C. Attribute docstrings and Additional docstrings are two types of extra docstrings that can be extracted by software tools.
- D. String Iiterals that occur in places other than the first statement in a module, function, or class definition can act as documentation They are recognized by the Python bytecode compiler and are accessible as runtime object attributes
正解：C
解説：
Explanation
The true statement related to PEP 257 is Option B. According to PEP 257, string literals occurring elsewhere in Python code may also act as documentation. They are not recognized by the Python bytecode compiler and are not accessible as runtime object attributes (i.e. not assigned to doc), but two types of extra docstrings may be extracted by software tools: String literals occurring immediately after a simple assignment at the top level of a module, class, or init method are called "attribute docstrings". String literals occurring immediately after another docstring are called "additional docstrings"1.
質問 # 48
Which of the following statements related to :memory: are true?
(Select two answers.)
- A. :memory: is a special name for creating a temporary database in the RAM.
- B. :memory: is a special name for loading a database from a file to the RAM.
- C. You can use :memory: to establish a database connection.
- D. You can use :memory: to delete a specific database that resides in the RAM.
正解：A、C
解説：
The correct answers are C and D. In Python's sqlite3 module, the string ':memory:' is passed to sqlite3.
connect() to create an in-memory SQLite database. This establishes a valid database connection, but the database exists only in RAM and normally disappears when the connection is closed. It is useful for testing, temporary storage, fast operations, and examples where no persistent database file is required.
Option A is wrong because :memory: does not load an existing file-based database into memory. Option B is also incorrect because it is not a deletion command or database management operation. It is simply a special database name recognized by SQLite to create a temporary in-memory database.
質問 # 49

A)
B)
C)
D)
An exception will be raised.
- A. Option C
- B. Option D

- D. Option B
正解：D
質問 # 50
Which of the following examples using line breaks and different indentation methods are compliant with PEP
8 recommendations? (Select two answers.)
- A.
- B.
- C.
- D.
正解：C、D
解説：
Explanation
The correct answers are B. Option B and D. Option D. Both options B and D are compliant with PEP 8 recommendations for line breaks and indentation. PEP 8 recommends using 4 spaces per indentation level and breaking lines before binary operators. In option B, the arguments to the print function are aligned with the opening delimiter, which is another acceptable way toformat long lines according to PEP 8. In option D, the second line is indented by 4 spaces to distinguish it from the next logical line.
質問 # 51
What is wrong with the following snippet?
class A:
def run(self):
print("A is running")
class B(A):
def run(self):
print("B is running")
class C(A, B):
def fly(self):
print("C is flying")
c = C()
- A. Nothing. The code is fine.
- B. There is no run() method defined for the C class.
- C. There are no __init__() methods - each class should implement this method.
- D. It causes MRO inconsistency.
正解：D
解説：
The issue is method resolution order, commonly called MRO. In Python multiple inheritance, the interpreter must build a consistent linear inheritance path for the class. Here, B already inherits from A, meaning B must appear before A in the resolution order. However, class C(A, B) asks Python to resolve A before B. These two requirements conflict, so Python cannot create a valid MRO for class C.
This results in a TypeError related to inconsistent method resolution order. The absence of an
__init__() method is not a problem because Python supplies a default initializer. Also, C can inherit run() if the inheritance order is valid.
