Select the true statements related to PEP 8 programming recommendations for code writing. (Choose two.)

• 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 isinstance() method (e.g. if isinstance(obj , int):) instead of comparing types directly (e.g. if type(obj) is type(1))
• 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

Which of the following values can be returned by the messagebox.askquestion() method?

• A. "accept" and "cancel"

• D. True and False

In the JSON processing context, the term serialization:

• A. names a process in which Python data is turned into a JSON string
• B. names a process in which a JSON string is turned into Python data
• 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

Select the true statement related to PEP 257.

• A. String literals that occur immediately after another docstring are called attribute docstrings
• B. Attribute docstrings and Additional docstrings are two types of extra docstrings that can be extracted by software tools
• C. String literals 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
• D. String literals that occur immediately after a simple assignment at the top level of a module are called complementary docstrings
