The value 3.14 is afloatbecause it contains a decimal point.

Example:

type(3.14)

This returns:

< class ' float ' >

Python’s built-in numeric types include integers and floating-point numbers. A value with a decimal part, such as 3.14, is treated as a floating-point number.

Therefore, the correct answer isB. Float.

An integrated terminal is built into a development environment or code editor. Its main advantage is that the developer can write code and run terminal commands in the same application.

This avoids switching back and forth between a separate terminal window and the code editor.

Therefore, the correct answer isC. Eliminates need to switch between applications.

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.

A list is a Python data structure that can store multiple values. Lists can contain duplicate values, and they support methods such as append() and remove().

Example:

fruits = [ " apple " , " banana " , " apple " ]

fruits.append( " orange " )

fruits.remove( " banana " )

print(fruits)

Output:

[ ' apple ' , ' apple ' , ' orange ' ]

The value " apple " appears more than once, showing that lists allow duplicates.

The official Python documentation lists list.append() as a method that adds an item to the end of a list and list.remove() as a method that removes the first matching value from a list.

Therefore, the correct answer is C. List.

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.

Step 1: The function receives one parameter named grades, which is a list of numbers.

Step 2: Use sum(grades) to add all the grades together.

Step 3: Use len(grades) to count how many grades are in the list.

Step 4: Divide the total by the number of grades.

Correct code:

def calculate_average(grades):

return sum(grades) / len(grades)

Example:

print(calculate_average([85, 92, 78]))

Output:

85.0

==========

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

Asetstores only unique elements. If duplicate values are added, Python keeps only one copy.

Example:

numbers = {1, 2, 2, 3}

print(numbers)

Output:

{1, 2, 3}

Python’s data structures documentation describes sets as collections with no duplicate elements.

Therefore, the correct answer isD. Set.

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.

To run a Python script from a text editor using the terminal on Windows, the file should first be saved with the .py extension. Then, the terminal is opened, and the script is executed using the Python command followed by the filename.

Example:

python filename.py

The official Python documentation explains that when the interpreter is called with a filename argument, it reads and executes the script from that file. On Windows, the python command can be used from a terminal after Python is installed and configured correctly.

Therefore, the correct answer is A. Save file > open terminal > type python filename.py.

==========

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

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.

==========

Step 1: The function receives the original price and the discount_percent.

Step 2: Convert the discount percentage into a decimal by dividing by 100.

Step 3: Subtract the discount from 1 to find the remaining price percentage.

Step 4: Multiply the original price by the remaining percentage.

Correct code:

def calculate_discount(price, discount_percent):

return price * (1 - discount_percent / 100)

Example:

print(calculate_discount(75, 20))

Output:

60.0

==========

Step 1: In Python, upper is a string method.

Step 2: A method must be called using parentheses ().

Step 3: text.upper refers to the method itself, but it does not execute it.

Step 4: Use text.upper() to return the uppercase version of the string.

Correct code:

def make_uppercase(text):

return text.upper()

Example:

print(make_uppercase( " hello " ))

Output:

HELLO

==========

Step 1: Python list indexing starts at 0.

Step 2: The first item is at index 0.

Step 3: The second item is at index 1.

Step 4: Return the value at index 1.

Correct code:

def get_second_item(items):

return items[1]

Example:

print(get_second_item([10, 20, 30]))

Output:

20
