Python Institute PCED - Certified Entry-Level Data Analyst with Python 認定 PCED-30-02 試験問題 (Q41-Q46):

質問 # 41
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[6:8].isdigit()returns True, and text.endswith("Final")returns True
C. text.isalpha()returns True, and text.find ("2024")returns True
D. text[-6].isdigit() returns True, text.startswith("r") returns True
E. text[0:6].isalpha() returns True, and text.find("2024") returns 6
F. text.capitalize()changes Report2024Finalto REPORT2024FINAL, and text.find("2024")returns 6

正解：A、B、E

解説：
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.

質問 # 42
Consider the following Python code:

What will be printed when the code above is executed?
40

A. [20, 30, 40]
1
[1, 2, 4, 5, 6]
50
B. [10, 20, 30, 40]
1
[1, 2, 4, 5, 6]
50
C. [10, 20, 30, 40]
0
[1, 2, 3, 4, 5, 6]
50
D. [20, 30, 40]
1
[1, 2, 4, 5, 6]

正解：D

解説：
The last element of the original list is 50. The slice from index 1 up to (but not including) index 4 is
[20, 30, 40]. After removing 30 and appending 60, the list contains one occurrence of 10, and integer division by 10 produces [1, 2, 4, 5, 6].

質問 # 43
A script defines a variable x = None and checks its truth value using a conditional statement. The developer wants to understand how Python evaluates None in Boolean contexts. What will bool(x) return?

A. False
B. Error
C. None
D. True

正解：A

解説：
The value None represents the absence of a value and is treated as False in Boolean expressions. Therefore, calling bool(None) returns False, similar to empty containers or zero values.

質問 # 44
Which task is traditionally or typically performed by a data analyst, and not by a data scientist or analytics specialist? Select the best answer.

A. Developing machine learning algorithms to predict user behavior.
B. Designing a data pipeline to ingest and process real-time sensor data.
C. Creating summary tables and charts to describe patterns in historical data.
D. Recommending pricing strategies using predictive modeling and A/B testing.

正解：C

解説：
Creating summary tables and charts to describe patterns in historical data is a core responsibility of a data analyst, focusing on descriptive analytics and reporting rather than building predictive models, machine learning systems, or engineering data pipelines.

質問 # 45
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. CSV, because it stores tabular data in plain text and is compatible with spreadsheet applications.
D. XML, because it automatically preserves spreadsheet formatting and charts.

正解：C

解説：
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.
