Python Institute PCPP1 - Certified Professional in Python Programming 1 認定 PCPP-32-101 試験問題 (Q53-Q58):

質問 # 53
Which of the following constants will be used if you do riot define the quoting argument in the writer method provided by the csv module?

A. csv.QUOTE_NONE
B. csv.QUOTE_NONNUMERIC
C. svQUOTE_ALL
D. csv.QUOTE_MINIMAL

正解：D

解説：
Explanation
If you do not define the quoting argument in the writer method provided by the csv module, the default quoting behavior is set to QUOTE_MINIMAL. This means that fields containing special characters such as the delimiter or newline character will be quoted, while fields that do not contain special characters will not be quoted.

質問 # 54
Analyze the code and choose the best statement that describes it.

A. The code is responsible for the support of the negation operator e.g. a = - a.
B. The code is erroneous
C. The code is responsible for the support of the inequality operator i.e. i =
D. ___ne___() is not a built-in special method

正解：C

解説：
Explanation
The correct answer is D. The code is responsible for the support of the inequality operator i.e. i != j. In the given code snippet, the __ne__ method is a special method that overrides the behavior of the inequality operator != for instances of the MyClass class. When the inequality operator is used to compare two instances of MyClass, the __ne__ method is called to determine whether the two instances are unequal.

質問 # 55
In the JSON processing context, the term serialization:

A. names a process in which a JSON string is turned into Python data.
B. names a process in which Python data is turned into a JSON string.
C. refers to nothing, because there is no such thing as JSON serialization.
D. names a process in which a JSON string is remodeled and transformed into a new JSON string

正解：B

解説：
In the JSON processing context, the term serialization: A. names a process in which Python data is turned into a JSON string.
Serialization refers to the process of converting a data object, such as a Python object, into a format that can be easily transferred over a network or stored in a file. In the case of JSON, serialization refers to converting Python data into a string representation using the JSON format. This string can be sent over a network or stored as a file, and later deserialized back into the original Python data object.
Reference: Official Python documentation on json: https://docs.python.org/3/library/json.html#json- serialization

質問 # 56
Select the true statements related to PEP 8 programming recommendations for exception handling. (Select two answers.)

A. When designing exception hierarchies, you should focus on stating that a problem occurred, rather than programmatically trying to answer the question about what actually went wrong.
B. You should generally limit the use of a "bare" except: clause and, whenever possible, use specific exceptions instead.
C. You should derive exceptions from the Exception class, rather than from the BaseException class.
D. You should generally use "bare" except: clauses, as they will not catch SystemExit and KeyboardInterrupt exceptions, making it more difficult to interrupt a program using keyboard shortcuts.

正解：B、C

解説：
The correct answers are C and D. Custom application exceptions should normally inherit from Exception, not directly from BaseException. BaseException is intended for system-exiting exceptions such as SystemExit, KeyboardInterrupt, and GeneratorExit, so deriving ordinary errors from it can interfere with normal control flow. PEP 8 also discourages broad or bare except: clauses because they catch too much and can hide programming errors or prevent expected interruption behavior. Specific exception handling is clearer, safer, and easier to debug. Option A reverses the intended guidance:
exception hierarchies should help code distinguish what went wrong programmatically. Option B is false because a bare except: can catch system-level exceptions, which is exactly why it should be avoided.

質問 # 57
Which of the following values can be returnedby the messagebox. askquestion () method?

A. "yes" and "no"
B. "accept:" and "cancel''
C. l and o
D. True and False

正解：A

解説：
Explanation
The messagebox.askquestion() method in Python's tkinter library displays a message box with a specified question and two response buttons labeled "Yes" and "No". It returns a string indicating which button was selected - either "yes" or "no".
This function is used to ask questions to the user that have only two options: YES or NO. It can be used to ask the user if they want to continue or if they want to submit something 1.
