QUESTIONS AND CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (MOST RECENT!!)
1. A Python script needs to store a configuration that consists
of key-value pairs (e.g., host:"localhost", port:8080). Which
data type is most appropriate for this?
A) List
B) Tuple
C) Set
D) Dictionary
<details> <summary><strong>Click for Answer &
Rationale</strong></summary>
Answer: D) Dictionary
Rationale: Dictionaries are the only built-in Python data type
specifically designed to store relationships as unordered key-
value pairs. While you could technically use two parallel lists, a
dictionary provides O(1) lookup time for values based on their
unique keys, which is essential for configuration management .

2. An IT administrator writes the following code: servers =
["Web1", "DB1", "App1"]. Later, they need to change "DB1" to
"DB2". What is the correct way to do this?

1

,A) servers[1] = "DB2"
B) servers{1} = "DB2"
C) servers[2] = "DB2"
D) servers.replace("DB1", "DB2")
<details> <summary><strong>Click for Answer &
Rationale</strong></summary>
Answer: A) servers[1] = "DB2"
Rationale: Python lists are mutable and support item assignment
using square bracket notation with the index. Indexing starts at
0, so the second element ("DB1") is at index 1. Option D uses a
string method that does not work on lists .

3. A script is designed to process a series of commands stored
in a tuple. Why would a developer choose a tuple over a list
for this specific purpose?
A) To ensure the sequence of commands cannot be accidentally
modified.
B) To allow for dynamic appending of new commands at runtime.
C) To improve the speed of sorting the commands alphabetically.
D) To enable the use of negative indexing.
<details> <summary><strong>Click for Answer &
Rationale</strong></summary>
Answer: A) To ensure the sequence of commands cannot be
accidentally modified.

2

,Rationale: Tuples are immutable data structures. Once created,
their elements cannot be changed, added, or removed. This
makes them ideal for protecting critical sequences or
configuration constants from accidental corruption by the script .

4. When examining a Python script, you notice consistent use
of 4 spaces before each line inside a for loop. What is the term
for this whitespace?
A) Concatenation
B) Annotation
C) Indentation
D) Declaration
<details> <summary><strong>Click for Answer &
Rationale</strong></summary>
Answer: C) Indentation
Rationale: Unlike many languages that use braces {}, Python
uses indentation (whitespace at the beginning of a line) to define
code blocks. Incorrect indentation will raise an IndentationError .
</details>


5. A variable status is assigned a value True. What data type is
this?
A) Integer
B) String
3

, C) Boolean
D) NoneType
<details> <summary><strong>Click for Answer &
Rationale</strong></summary>
Answer: C) Boolean
Rationale: In Python, the bool data type represents logical
values and can only be True or False (case-sensitive with capital
T and F). Booleans are fundamental for controlling the flow of
conditional logic .
</details>


6. You are debugging an automation script and encounter the
error: TypeError: can only concatenate str (not "int") to str. What
operation caused this?
A) "Server" + 10
B) "Server" * 10
C) 10 / "Server"
D) "Server" == 10
<details> <summary><strong>Click for Answer &
Rationale</strong></summary>
Answer: A) "Server" + 10
Rationale: Python is strongly typed. The + operator acts as
concatenation for strings but cannot combine a string with a non-
string type automatically. You must explicitly convert the integer
to a string using str(10) .
