Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q21-Q26):

NEW QUESTION # 21
Consider a Python program that assigns a string value "5" to a variable and then attempts to multiply it by an integer 3. The programmer expects numeric multiplication. What will actually happen when the code is executed?

A. "555"
B. 0
C. Error
D. 1

Answer: A

Explanation:
In Python, multiplying a string by an integer repeats the string. Therefore, "5" * 3 produces "555", not a numeric result. This behavior differs from arithmetic multiplication and often confuses beginners.

NEW QUESTION # 22
A financial technology company is reviewing its data practices to ensure legal and ethical compliance.
Which of the following actions would support responsible data handling and align with regulations like GDPR, HIPAA, and CCPA? (Choose two.)

A. Automatically opting users into data sharing unless they manually change settings.
B. Implementing encryption for both stored and transmitted customer data.
C. Providing users with a clear explanation of how their data is used and obtaining explicit consent.
D. Limiting data access only to marketing staff to streamline personalization.
E. Retaining user data permanently unless users explicitly request deletion.

Answer: B,C

Explanation:
Encrypting stored and transmitted data protects sensitive information from unauthorized access and supports regulatory requirements for data security. Providing clear explanations of data usage and obtaining explicit consent ensures transparency and aligns with core principles of data protection regulations such as lawful processing and user rights.

NEW QUESTION # 23
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?

A. fields = line.strip().split(', ')
B. fields = line.split(', ').trim()
C. fields = line.split().strip(', ')
D. fields = line.replace(', ', '|').split('|')

Answer: A

Explanation:
Stripping removes leading and trailing whitespace from the line, and then splitting on the comma- space delimiter correctly separates the values into a list for further formatting.
