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.

In Python, indentation determines which statements belong to an if block.

Example:

temperature = 30

if temperature > 25:

print( " It is warm. " )

print( " Drink water. " )

Both print() statements are executed when the condition is true because they share the same indentation level under the if statement.

Python does not use parentheses, semicolons, or square brackets to define the body of an if statement. It uses indentation.

Therefore, the correct answer isB. Lines that share the same indentation level.

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.

Step 1: Python string indexing starts at 0.

Step 2: The last valid index of a string is len(text) - 1, not len(text).

Step 3: Python also allows negative indexing, where -1 means the last character.

Step 4: Replace text[len(text)] with text[-1] .

Correct code:

def get_last_character(text):

return text[-1]

Example:

print(get_last_character( " Python " ))

Output:

n

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.

Step 1: The expression number % 2 == 0 checks whether the number is even.

Step 2: The original code writes True and False, but it does not return them.

Step 3: A function must use the return statement to send a value back to the caller.

Correct code:

def is_even(number):

if number % 2 == 0:

return True

else:

return False

Simplified correct code:

def is_even(number):

return number % 2 == 0

Example:

print(is_even(4))

print(is_even(7))

Output:

True

False

A Python for loop is used to iterate over an iterable object, such as a list, tuple, string, dictionary, set, or range() object.

A basic for loop needs:

A loop variable

An iterable object

An indented code block

Example:

for number in range(3):

print(number)

In this example:

number is the loop variable.

range(3) is the iterable.

print(number) is the indented code block that runs during each loop iteration.

According to the official Python documentation, the for statement is a construct that works with iterable objects.

Therefore, the correct answer is A. A variable, an iterable, and an indented code block.

In Python, an if statement line must end with a colon.

Example:

age = 18

if age > = 18:

print( " Adult " )

The colon : tells Python that an indented block of code follows. That indented block contains the statements that should run when the condition is true.

A semicolon, period, or comma is not used to begin the body of an if statement in Python.

Therefore, the correct answer is B. : colon.

A dictionary stores data as key-value pairs. In this function, the student name is the key, and the grade is the value.

Correct code:

def update_grade(grades, student, new_grade):

grades[student] = new_grade

return grades

Example:

update_grade({ " Alice " : 85, " Bob " : 90}, " Alice " , 95)

Result:

{ " Alice " : 95, " Bob " : 90}

Python’s built-in types documentation includes dictionaries as mapping types, where values are accessed and updated using keys.

Therefore, the correct answer isA.
