問題 #27
Which of the following types cannot be pickled?

A. strings, bytes, bytearrays
B. integers, floating-point numbers, complex numbers
C. function and class definitions
D. None, booleans

答案：C

解題說明：
The correct answer is B because Python's pickle module can serialize many built-in data types, including integers, floating-point numbers, complex numbers, strings, bytes, bytearrays, booleans, and None. However, it does not serialize the actual implementation or definition body of functions and classes. Top-level functions and classes may sometimes be pickled by reference using their fully qualified names, but their code definitions are not stored inside the pickle byte stream. This distinction matters: pickle records enough information to locate an object again during unpickling, but it does not preserve source code, nested definitions, lambda functions, or dynamically created definitions in a portable way. Therefore, "function and class definitions" is the option that cannot truly be pickled as definitions.

問題 #28
Select the true statements related to PEP 8 programming recommendations for code writing. (Select two answers:)

A. 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)).
B. You should not write string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them
C. You should write code in a way that favors the CPython implementation over PyPy, Cython. and Jython.
D. 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 notNone:), to increase readability.

答案：A,B

解題說明：
Explanation
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.

問題 #29
What is a static method?

A. A method that works on the class itself
B. A method decorated with the @method trait
C. A method that works on class objects that are instantiated
D. A method that requires no parameters referring to the class itself

答案：D

解題說明：
Explanation
A static method is a method that belongs to a class rather than an instance of the class. It is defined using the @staticmethod decorator and does not take a self or cls parameter. Static methods are often used to define utility functions that do not depend on the state of an instance or the class itself.

問題 #30
What is a___traceback___?
(Select two answers )

A. A special method delivered by the traceback module to retrieve a full list of strings describing the traceback
B. An attribute that holds interesting information that is particularly useful when the programmer wants to store exception details in other objects
C. An attribute that is added to every object when the traceback module is imported
D. An attribute owned by every exception object

答案：B,D

問題 #31
Which one of the following methods allows you to debug an XML tree in the xml.etree ELementTree module?

A. debug
B. dump
C. parse
D. log

答案：B

解題說明：
Explanation
The dump() method in the xml.etree.ElementTree module allows you to output a debug representation of an XML tree to a file or standard output. This method is useful for analyzing the structure of the tree and tracking down errors.
