Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q38-Q43):

NEW QUESTION # 38
Given the following string:
text = "Report2024Final"
Which of the following statements are entirely correct? (Choose two.)

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

Answer: C,D,E

Explanation:
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.

NEW QUESTION # 39
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. 0
B. Error
C. "555"
D. 1

Answer: C

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 # 40
Which of the following statements about Python functions are correct? (Choose two.)

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

Answer: C,F

Explanation:
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.

NEW QUESTION # 41
A Python developer is testing truth values of different data types using the bool() function. The expression bool([0]) is evaluated in the script. What result should be expected when this expression is printed?

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

Answer: C

Explanation:
In Python, any non-empty list evaluates to True in a Boolean context. Even though the element inside the list is zero, the list itself is not empty, so the result is True.

NEW QUESTION # 42
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.strip().capitalize()
B. cleaned_city = city.upper().strip()
C. cleaned_city = city.strip().title()
D. cleaned_city = city.upper().replace(" ", "")

Answer: C

Explanation:
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.
