質問 # 28
What is the result of the following code?

What is the result of the following code?

A. Nothing will be displayed
B. Debugging mode has been enabled Loading data...
C. Loading data...
D. Debugging mode has been enabled

正解：C

解説：
Explanation
This statement is true because the code uses the logging module to create a logger object and set its level to logging.INFO. The logging module provides a way of reporting events that occur during the execution of a program. The logging level determines which events are reported and which are ignored. The logging module defines five levels of severity: DEBUG, INFO, WARNING, ERROR, and CRITICAL. The lower the level, the more events are reported.
The code then uses the logger object to log two messages: one with the level logging.DEBUG and one with the level logging.INFO. The logger object only reports the messages that have a level equal or higher than its own level. Therefore, the message with the level logging.DEBUG is ignored, while the message with the level logging.INFO is reported. The default format for reporting messages is "level name: message". Therefore, the output of the code is:
INFO: Loading data...

質問 # 29
Analyze the following snippet and choose the best statement that describes it.

A. Excalibur is the value passed to an instance variable
B. Weapon is the value passed to an instance variable
C. self. name is the name of a class variable.
D. varl is the name of a global variable

正解：A

解説：
Explanation
The correct answer is C. Excalibur is the value passed to an instance variable. In the given code snippet, self.name is an instance variable of the Sword class. When an instance of the Sword class is created with varl = Sword('Excalibur'), the value 'Excalibur' is passed as an argument to the __init__ method and assigned to the name instance variable of the varl object.
The code defines a class called Sword with an __init__ method that takes one parameter name. When a new instance of the Sword class is created with varl = Sword('Excalibur'), the value of the 'Excalibur' string is passed as an argument to the __init__ method, and assigned to the self.name instance variable of the varl object.

質問 # 30
Analyze the following snippet and select the statement that best describes it.

A. The code is syntactically incorrect - the function should be defined as def f1 (*args, **kwargs)
B. The code is syntactically correct despite the fact that the names of the function parameters do not follow the naming convention
C. The code is missing a placeholder for unnamed parameters.
D. The *arg parameter holds a list of unnamed parameters

正解：D

解説：
Explanation
The provided code snippet defines a function f1 that accepts variable-length arguments using the *args and **kwargs syntax. The *args parameter allows for an arbitrary number of unnamed arguments to be passed to the function as a tuple, while the **kwargs parameter allows for an arbitrary number of named arguments to be passed to the function as a dictionary.
Therefore, the correct statement that best describes the code is:
The *args parameter holds a list of unnamed parameters, while the **kwargs parameter holds a dictionary of named parameters.

質問 # 31
Look at the following examples of comments and docstrings in Python. Select the ones that are useful and compliant with PEP 8 recommendations. (Select the two best answers.)

A. def total_cost(q):
'''Takes the q argument and multiplies it by 1.15.'''
return q * 1.15
B. def net_expense(q, price):
"""Return the total cost of items before tax."""
return q * price
C. n = n - 1 # Decrement n by 1.
D. val = val + 1.15 # Compensate for diminished value.

正解：B、D

解説：
The correct answers are A and C. Option A uses a concise one-line docstring that explains the function' s purpose in a useful way. It follows the common Python documentation style by describing what the function returns rather than repeating implementation mechanics. Option C is also useful because the inline comment explains why the value is being adjusted, not merely what the code already shows.
Option B is poor because it restates the obvious operation n = n - 1; such comments add noise instead of clarity. Option D is weaker because the docstring describes internal mechanics and argument handling rather than the function's intended result. Good Python comments should clarify intent, purpose, or non-obvious reasoning.

質問 # 32
Select the true statements related to PEP 8 naming conventions. (Select two answers.)

A. Modules should have short names entirely in lower-case.
B. Exception names should follow the function naming conventions.
C. Class names should use the mixedCase naming style.
D. You should never use the characters "l" (lower-case letter "el") and "O" (upper-case letter "oh") as single character variable names.

正解：A、D

解説：
The correct answers are C and D. PEP 8 recommends that module names should be short and entirely lower-case; underscores may be used only when they improve readability. This keeps imports clean and predictable. PEP 8 also warns against using the single-character variable names l, O, or I because they can be visually confused with 1 and 0 in many fonts. Option A is incorrect because Python class names should normally use the CapWords convention, not mixedCase. Option B is incorrect because exception names are class names and should follow class naming conventions; if the exception represents an error, the name should usually end with Error.
