Section A 30 Marksthis Section Is In Two Parts Part 1 Will Test You

This section is in two parts. Part 1 tests knowledge of Python language structure with multiple-choice questions, and Part 2 assesses general knowledge in Python through brief questions and programming tasks.

Part 2: General Knowledge in Python

  1. Mention 2 key features of Python.
  2. Describe when to use a tuple data structure rather than a list.
  3. Design a data structure using dictionaries and either lists or tuples to store class scores of students in three courses: ENGL 101, MATH 101, and SCI 101, using their index numbers.
  4. Identify and correct errors in a sample code that checks for palindrome words:

    word = ‘madam’

    rword = reversed(word)

    print(word == rword)

  5. Predict whether the following logical expression evaluates to True or False: score = 49; if (score
  6. Determine whether the statement = ‘’ evaluates to True or False: bool(statement)
  7. Evaluate whether x = -3; x > 0 and x
