An online retailer collects customer reviews, order transaction logs, and product ratings.
Which of the following correctly classifies these types of data? Select the best answer.

A. Product ratings are qualitative and unstructured; customer reviews are quantitative and structured; transaction logs are semi-structured and qualitative.
B. Product ratings are quantitative and structured; customer reviews are qualitative and unstructured; transaction logs are structured and quantitative
C. Product ratings are qualitative and structured; customer reviews are qualitative and unstructured; transaction logs are quantitative and semi-structured.
D. Product ratings are quantitative and unstructured; customer reviews are structured and qualitative; transaction logs are quantitative and unstructured.

Antwort: B

Begründung:
Product ratings are numeric values stored in fixed fields, making them quantitative and structured.
Customer reviews are free-text responses, which are qualitative and unstructured. Transaction logs consist of organized records with defined fields such as order ID, date, and amount, making them structured and quantitative.

32. Frage
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.isalpha()returns True, and text.find ("2024")returns True
D. text[0:6].isalpha() returns True, and text.find("2024") returns 6
E. text[6:8].isdigit()returns True, and text.endswith("Final")returns True
F. text.capitalize()changes Report2024Finalto REPORT2024FINAL, and text.find("2024")returns 6

Antwort: A,D,E

Begründung:
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.

33. Frage
Which of the following statements about Python functions are correct? (Choose two.)

A. passexecutes the function body and returns its result.
B. If a function does not contain a returnstatement, it returns Noneby default.
C. Functions can only return numeric values or strings.
D. Positional arguments must be passed in the order defined, while keyword arguments can be passed in any order using their parameter names.
E. Default parameters must always come before required ones in the parameter list.
F. A function cannot call itself or be passed as an argument to itself.

Antwort: B,D

Begründung:
Positional arguments are matched to parameters by their position, so they must follow the defined order, while keyword arguments are matched by name and can be provided in any order. If a function completes without an explicit return statement, Python returns None automatically.

34. Frage
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?

A. 0
B. 1
C. 2
D. 3

Antwort: A

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

35. Frage
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.replace(', ', '|').split('|')
C. fields = line.split().strip(', ')
D. fields = line.split(', ').trim()

Antwort: A

Begründung:
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.
