최신 Python Institute PCED PCED-30-02 무료샘플문제 (Q24-Q29):

질문 # 24
A loop is designed using range(1, 6, 2) to iterate through numbers. The developer wants to know exactly which values will be generated during execution. Which sequence correctly represents the values produced?

A. 1, 2, 3, 4, 5
B. 2, 4, 6
C. 1, 3
D. 1, 3, 5

정답：D

설명：
The range(start, stop, step) function generates numbers starting from 1, increasing by 2, and stopping before 6. Therefore, the resulting sequence is 1, 3, and 5.

질문 # 25
Given the following string:
text = "Report2024Final"
Which of the following statements are entirely correct? (Choose two.)

A. text.capitalize()changes Finalto lowercase, and text.find ("L")returns True
B. text[-6].isdigit() returns True, text.startswith("r") returns True
C. text[6:8].isdigit()returns True, and text.endswith("Final")returns True
D. text[0:6].isalpha() returns True, and text.find("2024") returns 6
E. text.capitalize()changes Report2024Finalto REPORT2024FINAL, and text.find("2024")returns 6
F. text.isalpha()returns True, and text.find ("2024")returns True

정답：A,C,D

설명：
The slice text[6:8] is "20", which contains only digits, and the string ends with "Final". The first six characters are "Report", which are all alphabetic, and "2024" begins at index 6.

질문 # 26
An e-commerce site records every product view and purchase.
Which of the following best describes how these logs become marketing insights?

A. Raw event logs are filtered, aggregated, and formatted into summaries - like total visits per category - which then provide traffic reports.
B. Raw event logs are structured, analyzed, and interpreted into information - like conversion rates by product - which then builds knowledge of customer preferences.
C. Raw event logs are stored, archived, and indexed - like by user ID and session - which then facilitate audit trails.
D. Raw event logs are validated, organized, and compiled into datasets - like timestamped user actions - which then support system debugging.

정답：B

설명：
Marketing insights are produced when raw event logs are structured, analyzed, and interpreted to generate meaningful metrics such as conversion rates. These interpreted results transform data into actionable knowledge about customer behavior and preferences.

질문 # 27
A data analyst exports a cleaned dataset from Python and wants to share it with a colleague for easy use in Excel.
Which file format is best suited for this purpose? Select the best answer.

A. SQL, because it directly converts tabular data into database tables that Excel can open.
B. JSON, because it stores hierarchical data and is designed for visual presentation in Excel.
C. XML, because it automatically preserves spreadsheet formatting and charts.
D. CSV, because it stores tabular data in plain text and is compatible with spreadsheet applications.

정답：D

설명：
CSV stores tabular data in a simple plain-text, comma-separated format that is widely supported by spreadsheet applications like Excel, making it ideal for sharing datasets for easy import and analysis.

질문 # 28
A Python loop uses range(5, 0, -2) to iterate backward. The programmer expects a decreasing sequence. Which values will actually be generated when this loop runs?

A. 4, 2, 0
B. 5, 3, 1
C. 5, 4, 3, 2, 1
D. 5, 3

정답：B

설명：
The range starts at 5 and decreases by 2 each step until it reaches a value greater than 0. The generated sequence is 5, 3, and 1.
