Python Institute PCED - Certified Entry-Level Data Analyst with Python Sample Questions (Q31-Q36):

NEW QUESTION # 31
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. None
B. False
C. Error
D. True

Answer: B

Explanation:
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.

NEW QUESTION # 32
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[6:8].isdigit()returns True, and text.endswith("Final")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.capitalize()changes Finalto lowercase, and text.find ("L")returns True
F. text.capitalize()changes Report2024Finalto REPORT2024FINAL, and text.find("2024")returns 6

Answer: B,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 # 33
Consider the following Python code:

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

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

Answer: B

Explanation:
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].

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

Answer: D

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.
