                          質問 # 39
                          You have a list of test scores, where each entry includes a student name and a score. Some students appear more than once. You want to compute the average score for each student and store the results in a dictionary. Here's the partial code block:

                          Which code correctly replaces the # MISSING CODE comment to calculate the average score for each student? Select the best answer.

                          正解:C

                          解説:
                          It iterates through each record, extracts the name and score, and uses dictionary .get() to accumulate total scores and counts per student safely, initializing missing keys to zero. This correctly enables calculation of each student's average afterward.


                          質問 # 40
                          You are reading a data.csvfile line by line. To prepare each line for formatting with f-strings, you need to remove extra whitespace and split the values by commas.
                          Which line should you insert to correctly clean and parse the input?

                          正解:B


                          質問 # 41
                          A programmer writes a script to test operator precedence using the expression 3 + 4 * 2 ** 2. The goal is to evaluate the result correctly based on Python's operator hierarchy rules. What result should the script produce?

                          正解:B

                          解説:
                          Exponentiation is evaluated first, so 2 ** 2 equals 4. Then multiplication 4 * 4 equals 16. Finally, addition is performed: 3 + 16 results in 19.


                          質問 # 42
                          A Python script checks membership using "a" in "apple". The developer wants to understand how membership works for strings. What result will this expression produce?

                          正解:B

                          解説:
                          The in operator checks for substring presence. Since the character "a" exists in "apple", the expression evaluates to True, demonstrating how membership works for strings in Python.


                          質問 # 43
                          A government agency collects citizen data for various public services.
                          What is the primary reason for emphasizing careful data management throughout the entire data lifecycle in this context? Select the best answer.

                          正解:A

                          解説:
                          Careful data management across the entire lifecycle ensures high data quality for reliable public services, protects sensitive citizen information from misuse, and maintains compliance with legal and regulatory data protection requirements.
