Question Breakdown

1. Valid Variable Names in Python (Circle valid names):

   • Options: Int, lab, 12, 10cents, avg_value

2. Expression Values (Given Values):

   • Assignments:

     • e = 3

     • h = 2.8

     • f = 14

     • g = 20

     • m = [1, 2, 3, 4, 5, 6]

   • Evaluation and errors on expressions:

     • a) h + f // g: yields a value

     • b) g + f)/int(h) + m[2]: yields a value

     • c) g - -18**(e * m[1])**(g // m[5]) - f): yields a value

     • d) Length of j: raises an error

     • e) m + 7 - 6/2 + 3: yields a value

3. True/False Conditions:

   • Evaluate logical conditions for truth value.

4. Loop Iterations:

   • Analyze iterations of for loops using range:

   • a) for x in range(27, 8, -3): 9 iterations

   • b) for k in range(4, 13): 9 iterations

5. Python Code Writing:

   • a) Create a list of evens:

     evens = [x for x in range(2, 2001, 2)]

   • b) Create a tuple:

tictactoe = ('win', 'loss', 'tie') * 30 ```

• c) Create a dictionary:

  checkout = {1: [3, 89, 2.99], 2: [55, 44, 1.99]}

6. Identifying Immutable Types:

   • Lists

   • Strings

   • Tuples

   • Dictionaries

   • Range objects

7. Output from Code:

   • a) From concatenation of lists and tuples: Choose correct output

   • b) Accessing list of lists: Identify correct accessed element

   • c) g.remove(3): Length after removal

   • d) String replacement examples

   • e) Determine output after insert function

8. Assessing Code Outputs:

   • a) Lambda function: trace its output

   • b) Error checking with logic statements

   • c) Formatting issues in print statements

   • d) Dictionary operations translate into print

9. Outputs for Given Code Blocks:

   • a) Finding substring in a string

   • b) List comprehensions based on another list

10. Function Definitions Required:

• load_pos function:

  • Handles file input, reads until sentinel value 0

  • Includes logic to append positive values to a list.

• count_list function:

  • Takes positive values from list and counts occurrences, returning a new list.
