Python Institute PCED - Certified Entry-Level Data Analyst with Python 認定 PCED-30-02 試験問題 (Q34-Q39):

質問 # 34
You are working with city names entered by users. These names may contain inconsistent capitalization and unwanted spaces.
To standardize the data, you want to:
- Remove any leading or trailing whitespace, and
- Capitalize the first letter of each word (e.g., convert "new york" to "New York").
For example:
" New york " → "New York"
"lOS ANGELES" → "Los Angeles"
You are given a variable citythat contains the raw input.
Which line of code correctly updates the value of cleaned_cityto apply the required transformation? Select the best answer.

A. cleaned_city = city.upper().replace(" ", "")
B. cleaned_city = city.upper().strip()
C. cleaned_city = city.strip().capitalize()
D. cleaned_city = city.strip().title()

正解：D

解説：
Stripping removes leading and trailing whitespace, and applying title formatting capitalizes the first letter of each word while converting the remaining letters to lowercase, producing the correctly standardized city name.

質問 # 35
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.

A. To guarantee the long-term availability and integrity of crucial citizen datasets for future policy formulation and evaluation.
B. To streamline the initial capture of citizen details and minimize the administrative burden on both staff and the public.
C. To uphold data quality for effective service delivery, safeguard citizen privacy and prevent misuse, and comply with data protection laws.
D. To enable seamless sharing of anonymized citizen information with other governmental bodies for collaborative initiatives.

正解：C

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.

質問 # 36
A dictionary is defined as d = {"a":1, "b":2}. The programmer accesses d["c"]. What happens when this line executes?

A. Returns 0
B. Raises KeyError
C. Returns None
D. Adds key automatically

正解：B

解説：
Accessing a non-existent key using square brackets raises a KeyError. Python does not automatically create missing keys, so the program will terminate unless the exception is handled.

質問 # 37
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 validated, organized, and compiled into datasets - like timestamped user actions - which then support system debugging.
B. Raw event logs are filtered, aggregated, and formatted into summaries - like total visits per category - which then provide traffic reports.
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 structured, analyzed, and interpreted into information - like conversion rates by product - which then builds knowledge of customer preferences.

正解：D

解説：
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.

質問 # 38
A program uses while False: followed by print statements inside the loop. The developer expects output. What will actually happen during execution?

A. Error
B. Infinite loop
C. No execution
D. Prints once

正解：C

解説：
The condition False is evaluated before entering the loop. Since it is always false, the loop body is never executed, and no output is produced.
