Book excerpt: PCAP Certified Associate in Python Programming Certification is a comprehensive mock exam with emphasis on using the PCAP-31-03 Syllabus as guide on the question topic. The audience should have basic knowledge in Python or have a good grasp on other programming language because this is not a tutorial. All 286 questions are based on individual topics in the syllabus and all topics have been covered. Each and every topic in the syllabus have a corresponding question with sufficient representation. Exam block #1: Modules and Packages (46 questions) Objectives covered by the block (6 items) import variants; advanced qualifiying for nested modules dir(); sys.path variable math: ceil(), floor(), trunc(), factorial(), hypot(), sqrt(); random: random(), seed(), choice(), sample() platform: platform(), machine(), processor(), system(), version(), python_implementation(), python_version_tuple() idea, __pycache__, __name__, public variables, __init__.py searching for modules/packages; nested packages vs directory tree Exam block #2: Exceptions (41 questions) Objectives covered by the block (5 items) except, except:-except; except:-else:, except (e1,e2) the hierarchy of exceptions raise, raise ex, assert event classes, except E as e, arg property self-defined exceptions, defining and using Exam block #3: Strings (42 questions) Objectives covered by the block (8 items) ASCII, UNICODE, UTF-8, codepoints, escape sequences ord(), chr(), literals indexing, slicing, immutability iterating through, concatenating, multiplying, comparing (against strings and numbers) in, not in .isxxx(), .join(), .split() .sort(), sorted(), .index(), .find(), .rfind() Exam block #4: Object-Oriented Programming (49 questions) Objectives covered by the block (12 items) ideas: class, object, property, method, encapsulation, inheritance, grammar vs class, superclass, subclass instance vs class variables: declaring, initializing __dict__ property (objects vs classes) private components (instance vs classes), name mangling methods: declaring, using, self parameter instrospection: hasattr() (objects vs classes), __name__, __module__, __bases__ properties inheritance: single, multiple, isinstance(), overriding, not is and is operators constructors: declaring and invoking polymorphism __name__, __module__, __bases__ properties, __str__() method multiple inheritance, diamonds Exam block #5: Miscellaneous (List Comprehensions, Lambdas, Closures, and I/O Operations) (44 questions) Objectives covered by the block (4 items) list comprehension: if operator, using list comprehensions lambdas: defining and using lambdas, self-defined functions taking lambda as as arguments; map(), filter(); closures: meaning, defining, and using closures I/O Operations: I/O modes, predefined streams, handles; text/binary modes open(), errno and its values; close() .read(), .write(), .readline(); readlines() (along with bytearray()) Bonus block (64 questions) Objectives covered by the block (1 item) Uncategorized topics from PCAP-31-01, PCAP-31-02 and PCAP-NP-31-02 Questions in the Practice tests are much more difficult than what is included in the Certified Associate in Python Programming Certification. I recommend doing hands-on to test the validity of the answers and emphasize on the importance of coding different permutations and combinations on the examples given. All questions are self-explanatory and it will be easier to understand if the code is run on IDLE or the user's preferred Python IDE.
