Q21. Complete the function format_name(first, last) that takes a first name and last name and returns them combined as ” last, first ” .
For example, format_name( ” John ” , ” Smith ” ) should return ” Smith, John ” .
def format_name(first, last):
# TODO: Return the name in ” last, first ” format
pass

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives two string parameters: first and last.
Step 2: The required format is the last name first, followed by a comma, a space, and then the first name.
Step 3: Use string concatenation to combine the values correctly.
Correct code:
def format_name(first, last):
return last + ” , ” + first
Example:
print(format_name( ” John ” , ” Smith ” ))
Output:
Smith, John

Q22. Which components are required in every Python while loop?

A condition and an indented code block

A variable and a return statement

A counter and a break statement

An iterator and a list

A Python while loop needs a condition and an indented code block.
Example:
count = 1
while count < = 3:
print(count)
count += 1
The condition is count < = 3. The indented block contains the code that runs while the condition is true.
Python’s compound statement documentation includes while as a control-flow statement.
Therefore, the correct answer isA. A condition and an indented code block.

Q23. Fix the off-by-one error in this function that should return the first 3 characters of a string.
def first_three(text):
return text[0:2]

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: Python string slicing uses this format:
text[start:stop]
Step 2: The start index is included.
Step 3: The stop index is excluded.
Step 4: To return the first 3 characters, start at index 0 and stop at index 3.
Correct code:
def first_three(text):
return text[0:3]
Simplified correct code:
def first_three(text):
return text[:3]
Example:
print(first_three( ” Python ” ))
Output:
Pyt

Q24. Which keyword is used to exit a loop prematurely in Python?

return

break

stop

end

The break keyword exits a loop immediately before the loop condition naturally becomes false or before all items have been processed.
Example:
for number in range(10):
if number == 5:
break
print(number)
When number becomes 5, the loop stops. Python’s control-flow documentation explains the use of break in loops.
Therefore, the correct answer isB. break.

Q25. Which keyword moves a loop immediately to its subsequent iteration?

pass

jump

continue

advance

The Python keyword continue is used inside a loop to skip the rest of the current iteration and move immediately to the next iteration.
Example:
for number in range(5):
if number == 2:
continue
print(number)
Output:
0
1
3
4
When number is 2, the continue statement skips print(number) for that iteration and moves to the next loop cycle.
The official Python documentation states that the continue statement continues with the next iteration of the loop.
Therefore, the correct answer is C. continue.

Q26. Which Python data structure cannot be modified after creation?

List

Dictionary

Tuple

Set

Atupleis immutable, which means it cannot be changed after it is created.
Example:
coordinates = (10, 20)
After this tuple is created, its elements cannot be modified directly. Python’s data model documentation explains that tuples are immutable, while lists and dictionaries are mutable.
Therefore, the correct answer isC. Tuple.

Q27. A program needs to update all values in a list by adding 5 to each number. Which for loop structure accomplishes this task?

for number in numbers:number = number + 5

for i in range(len(numbers)):numbers[i] = numbers[i] + 5

for numbers in number:numbers = numbers + 5

To update the actual values inside a list, the program must update each value by itsindex.
The correct code is:
for i in range(len(numbers)):
numbers[i] = numbers[i] + 5
Here, range(len(numbers)) produces valid index positions for the list. The variable i is used to access and update each list element.
Example:
numbers = [10, 20, 30]
for i in range(len(numbers)):
numbers[i] = numbers[i] + 5
print(numbers)
Output:
[15, 25, 35]
Option A does not correctly update the original list:
for number in numbers:
number = number + 5
This changes only the temporary loop variable number, not the actual elements stored inside the list.
Therefore, the correct answer isB.

Q28. A dictionary prices = { ‘ apple ‘ : 1.50, ‘ banana ‘ : 0.75, ‘ orange ‘ : 2.00} needs to have all values increased by
0.25. Which code correctly accomplishes this task?

for item in prices:prices[item] = prices[item] + 0.25

for value in prices:value = value + 0.25

for prices in item:prices = prices + 0.25

In Python, iterating directly over a dictionary gives itskeys. In this dictionary, the keys are:
‘ apple ‘
‘ banana ‘
‘ orange ‘
To update each price, the program can loop through each key and use that key to access and change the corresponding value.
Correct code:
prices = { ‘ apple ‘ : 1.50, ‘ banana ‘ : 0.75, ‘ orange ‘ : 2.00}
for item in prices:
prices[item] = prices[ item] + 0.25
print(prices)
Output:
{ ‘ apple ‘ : 1.75, ‘ banana ‘ : 1.0, ‘ orange ‘ : 2.25}
Option B is incorrect because value actually receives each dictionary key, not each dictionary value. Also, assigning to value would not update the dictionary.
Option C is incorrect because item is not defined, and the loop structure is invalid for this task.

Q29. A program needs to display only positive, non-zero numbers from a list containing a mixture of integer and decimal values. Which conditional statement should be placed inside the loop?

if number > 0:

if number != 0:

if number < 0:

if number > = 1:

To display only positive, non-zero numbers, the condition should check whether each number is greater than 0.
Correct condition:
if number > 0:
Example:
numbers = [-2, 0, 1, 3.5, -4.2]
for number in numbers:
if number > 0:
print(number)
Output:
1
3.5
The condition number > 0 works for both integers and decimal values. The condition number > = 1 would incorrectly exclude positive decimal values such as 0.5.
Therefore, the correct answer isA. if number > 0:.

Q30. Complete the function get_max(a, b) that returns the larger of two numbers. If they are equal, return either one.
def get_max(a, b):
# TODO: Return the larger of a and b
pass

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives two parameters: a and b.
Step 2: Compare the two values using an if statement.
Step 3: If a is greater than or equal to b, return a.
Step 4: Otherwise, return b.
Correct code:
def get_max(a, b):
if a > = b:
return a
else:
return b
Simplified correct code:
def get_max(a, b):
return max(a, b)
Example:
print(get_max(10, 20))
print(get_max(30, 15))
print(get_max(5, 5))
Output:
20
30
5

Q31. What must a developer do to run Python code written in a text editor?

Save the file and use a Python interpreter.

Press a run button within the editor.

Upload the code to a web server.

Convert the code to machine language first.

When Python code is written in a text editor, the developer should save the file, usually with a .py extension, and run it using the Python interpreter.
Example terminal command:
python script.py
Python’s documentation explains that a Python module is a file containing Python definitions and statements, usually saved with the .py suffix.
Therefore, the correct answer isA. Save the file and use a Python interpreter.

Q32. Which data type does the expression 5 > 3 evaluate to in Python?

Integer

String

Boolean

Float

In Python, comparison expressions such as 5 > 3 evaluate to aBooleanvalue.
The expression:
5 > 3
checks whether 5 is greater than 3. Since this statement is true, Python returns:
True
True and False are Boolean values in Python.
Therefore, the correct answer isC. Boolean.

Q33. Which terminal command is used to navigate to a different directory before running a Python script?

move

goto

nav

The command cd means “change directory.” It is used in a terminal to move from one folder to another.
Example:
cd Desktop
After navigating to the correct folder, a Python script can be run with a command such as:
python script.py
Therefore, the correct answer isC. cd.

Q34. Which tool is used to execute Python code line-by-line interactively within a terminal?

Python shell

Text editor

File explorer

Debugger

The Python shell allows Python code to be entered and executed interactively, one line at a time.
Example:
> > > 2 + 3
5
Python’s documentation explains that when commands are read from a terminal, the interpreter is in interactive mode and prompts for the next command.
Therefore, the correct answer isA. Python shell.

Q35. In the code for item in my_list:, what does item represent?

The length of the list

The index of the current element

The current element being processed

The entire list

Q36. What must be consistent within a Python code block for the code to run without syntax errors?

Variable names

Indentation level

Comment placement

Line length

In Python, indentation is used to group statements into a code block. A block must have a consistent indentation level so Python can correctly understand which statements belong together.
For example:
if True:
print( ” Hello ” )
print( ” World ” )
Both print() statements belong to the same if block because they use the same indentation level.
If indentation is inconsistent, Python can raise an IndentationError or TabError.
Therefore, the correct answer isB. Indentation level.

Q37. What happens when theRunbutton is clicked in a Python development environment?

A file browser window opens.

The currently open Python script is executed.

The file is saved without being executed.

The code is converted to a different programming language.

In a Python development environment, clicking theRunbutton generally executes the currently open Python script or selected code.
For example, if the current script contains:
print( ” Hello, Python! ” )
clickingRunexecutes the script and displays the output:
Hello, Python!
In Python’s IDLE environment, theRun Modulecommand runs the current module. The Python documentation describes IDLE as Python’s editor and shell and includes a Run menu for running Python code.
The Run button does not simply open a file browser, save the file without execution, or convert Python code into another programming language.
Therefore, the correct answer isB. The currently open Python script is executed.

Q38. Which Python data structure contains only unique elements and does not support indexing?

List

Tuple

Dictionary

Set

A set is a Python data structure that stores only unique elements. This means duplicate values are automatically removed.
Example:
numbers = {1, 2, 2, 3}
print(numbers)
Output:
{1, 2, 3}
The duplicate value 2 appears only once in the set.
Sets are also unordered, so they do not support indexing like lists or tuples do. For example, numbers[0] would cause an error because sets are not accessed by position.
The official Python documentation describes sets as unordered collections with no duplicate elements.
Therefore, the correct answer is D. Set.

Q39. Which type of loop repeatedly checks a condition to determine whether to continue?

for loop

while loop

range loop

repeat loop

Awhile looprepeatedly executes a block of code as long as its condition remains true.
Example:
count = 1
while count < = 3:
print(count)
count += 1
In this example, Python checks the condition count < = 3 before each loop iteration. If the condition is true, the loop continues. When the condition becomes false, the loop stops.
A for loop is usually used to iterate over a sequence, such as a list, string, or range. Python does not have a built-in repeat loop construct.
Therefore, the correct answer isB. while loop.

Q40. Write a complete function password_strength(password) that returns ” Strong ” if the password is at least 8 characters long and contains both letters and numbers, ” Weak ” otherwise.
For example, password_strength( ” abc123def ” ) should return ” Strong ” .
def password_strength(password):
# TODO: Return ” Strong ” or ” Weak ” based on password criteria
if len(password) < 8:
return ” Weak “
has_letter = False
has_number = False
for char in password:
if char.isalpha():
has_letter = True
elif char.isdigit():
has_number = True
# TODO: Add your return logic here based on has_letter and has_number
pass

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: First, check the password length using len(password).
Step 2: If the password has fewer than 8 characters, return ” Weak ” immediately.
Step 3: Create two Boolean variables: has_letter and has_number.
Step 4: Loop through each character in the password.
Step 5: Use .isalpha() to check for letters and .isdigit() to check for numbers.
Step 6: If the password contains both at least one letter and at least one number, return ” Strong ” .
Step 7: Otherwise, return ” Weak ” .
Correct code:
def password_strength(password):
if len(password) < 8:
return ” Weak “
has_letter = False
has_number = False
for char in password:
if char.isalpha():
has_letter = True
elif char.isdigit():
has_number = True
if has_letter and has_number:
return ” Strong “
else:
return ” Weak “
Example:
print(password_strength( ” abc123def ” ))
print(password_strength( ” abcdefgh ” ))
print(password_strength( ” 12345678 ” ))
Output:
Strong
Weak
Weak

Q41. Modify the function greet_with_default(name) by adding a default value of ” World ” to the name parameter so it can be called with or without an argument.
def greet_with_default(name):
# TODO: Add a default value of ” World ” to the name parameter
return ” Hello ” + name

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: A default parameter value allows a function to be called even when no argument is provided.
Step 2: The default value should be added in the function header.
Step 3: The parameter name should have the default value ” World ” .
Correct code:
def greet_with_default(name= ” World ” ):
return ” Hello ” + name
Example:
print(greet_with_default())
print(greet_with_default( ” Alice ” ))
Output:
Hello World
Hello Alice

Q42. Write a complete function reverse_string(text) that takes a string and returns it reversed.
For example, reverse_string( ” hello ” ) should return ” olleh ” .
def reverse_string(text):
# TODO: Return the reversed string
pass

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives one string parameter named text.
Step 2: Python slicing can be used to reverse a string.
Step 3: The slice [::-1] means start at the end of the string and move backward by one character at a time.
Step 4: Return text[::-1].
Correct code:
def reverse_string(text):
return text[::-1]
Example:
print(reverse_string( ” hello ” ))
Output:
olleh

Q43. In the code for item in my_list:, what does item represent?

The index of the current element

The current element being processed

The length of the list

The entire list

In the loop:
for item in my_list:
print(item)
item represents the current element from my_list during each loop iteration.
For example:
my_list = [ ” apple ” , ” banana ” ]
for item in my_list:
print(item)
The loop first processes ” apple ” , then ” banana ” . Python’s documentation explains that a for statement iterates over the items of a sequence in order.
Therefore, the correct answer isB. The current element being processed.

Q44. Complete the function get_dict_keys(data) that takes a dictionary and returns a list of all its keys.
For example, get_dict_keys({ ” name ” : ” John ” , ” age ” : 25}) should return [ ” name ” , ” age ” ].
def get_dict_keys(data):
# TODO: Return a list of all dictionary keys
pass

See the Step by Step Solution below in Explanation.
Explanation:
Step 1: A dictionary stores data as key-value pairs.
Step 2: The .keys() method returns the dictionary’s keys.
Step 3: To return the keys as a list, use list(data.keys()).
Correct code:
def get_dict_keys(data):
return list(data.keys())
Example:
print(get_dict_keys({ ” name ” : ” John ” , ” age ” : 25}))
Output:
[ ‘ name ‘ , ‘ age ‘ ]

Q45. Which for loop correctly iterates through a list of student names?

for name in [ ‘ Alice ‘ , ‘ Bob ‘ , ‘ Carol ‘ ]:

for name with [ ‘ Alice ‘ , ‘ Bob ‘ , ‘ Carol ‘ ]:

for name from [ ‘ Alice ‘ , ‘ Bob ‘ , ‘ Carol ‘ ]:

for name = [ ‘ Alice ‘ , ‘ Bob ‘ , ‘ Carol ‘ ]

The correct Python for loop syntax uses the keyword in.
Correct code:
for name in [ ‘ Alice ‘ , ‘ Bob ‘ , ‘ Carol ‘ ]:
print(name)
This loop processes each name in the list one at a time. Python’s documentation explains that a for statement iterates over the items of a sequence or iterable.
Therefore, the correct answer isA. for name in [ ‘ Alice ‘ , ‘ Bob ‘ , ‘ Carol ‘ ]:.
