FPSC- Programmer (BS-17) - PMD High Yield - 2026 — Test 8

Correct Answer: B. 5 times; i = 11
Explanation: i takes the values 1, 3, 5, 7, and 9. The final increment to 11 makes the loop exit. ALSO KNOW (related points): • When is the body of a VB Do ... Loop While condition loop guaranteed to run at least once? → Always, because the condition is tested at the end • What does a Do Until x > 10 ... Loop loop do? → It repeats while x > 10 is False, and stops once it becomes True

Correct Answer: C. 12
Explanation: Val reads leading numeric characters and stops at the first non-numeric one. Val("abc") returns 0. ALSO KNOW (related points): • What does InStr("Hello", "l") return in VB? → 3 • What does Val("1 2 3") return in VB? → 123

Correct Answer: C. "kist"
Explanation: VB string positions are 1-based. Mid takes 4 characters starting at position 3. ALSO KNOW (related points): • What does InputBox return when the user clicks Cancel? → An empty string ("")

Correct Answer: D. [0, 1, 2] []
Explanation: A generator can be iterated only once. After it is exhausted, it yields nothing. ALSO KNOW (related points): • What does this print?: d = {'a': 1}; print(d.get('b'), d.get('b', 0)) → None 0 • What does print(type(range(5))) show in Python 3? → <class 'range'>

Correct Answer: A. [(1, 'a'), (2, 'b')]
Explanation: zip stops at the shortest input. itertools.zip_longest pads the shorter input instead. ALSO KNOW (related points): • What happens when keys are added to a dict while iterating over it in Python 3? → RuntimeError: dictionary changed size during iteration • What does sorted(['bb', 'a', 'ccc'], key=len, reverse=True) return? → ['ccc', 'bb', 'a'] • What does a lambda's body consist of in Python? → A single expression; statements such as assignment or return are not allowed

Correct Answer: C. [2, 3]
Explanation: Starred assignment always produces a list, even when the right side is a tuple. ALSO KNOW (related points): • What happens with ",".join([1, 2, 3])? → TypeError: sequence item 0: expected str instance, int found

Correct Answer: C. append gives [1, [2, 3]]; extend gives [1, 2, 3]
Explanation: append adds a single object. extend adds each element of an iterable. ALSO KNOW (related points): • What does open('data.txt', 'w') do when the file already exists? → It truncates the file to empty

Correct Answer: B. ['a', 'b', '', 'c']
Explanation: An explicit separator keeps empty fields. split() with no argument splits on runs of whitespace and drops empty strings. ALSO KNOW (related points): • What does map(str, [1, 2]) return in Python 3? → A lazy map iterator object • What does 'Python'[::-1] return? → 'nohtyP' • What does ' a b '.split() return? → ['a', 'b']

Correct Answer: B. find returns -1; index raises ValueError
Explanation: Choose find when a missing substring is a normal case, and index when it is an error. ALSO KNOW (related points): • What happens with a, b = [1, 2, 3]? → ValueError: too many values to unpack • What does int("3.5") do? → It raises ValueError • What is the difference between @staticmethod and @classmethod? → A classmethod receives the class (cls) as its first argument; a staticmethod receives no implicit first argument • What is the difference between print in Python 2 and Python 3? → In Python 3, print is a function and needs parentheses; in Python 2, it was a statement

Correct Answer: C. No; it prints 10
Explanation: Comprehensions have their own scope in Python 3. In Python 2, the variable leaked. ALSO KNOW (related points): • What does print(*[1, 2, 3], sep='-') print? → 1-2-3
