Câu 25: PCPP-32-101: Certified Professional in Python Programming 1

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

1. 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.
2. 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)). — đáp án hiện tại
3. C. You should write code in a way that favors the CPython implementation over PyPy, Cython, and Jython.
4. 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. — đáp án hiện tại
