==========

Step 1: The function receives one parameter named celsius.

Step 2: Use the formula:

F = C * 9 / 5 + 32

Step 3: Return the converted Fahrenheit value.

Correct code:

def convert_temperature(celsius):

return celsius * 9 / 5 + 32

Example:

print(convert_temperature(0))

Output:

32.0

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.

The correct function uses the list method append() to add new_number to the end of numeric_list.

Correct code:

def add_item(numeric_list, new_number):

numeric_list.append(new_number)

return numeric_list

Example:

add_item([1, 2, 3], 4)

Result:

[1, 2, 3, 4]

Python’s data structures documentation explains that list.append(x) adds an item to the end of the list.

Therefore, the correct answer isA.

The .find() method returns the lowest index where the searched substring is found.

Example:

" learning python programming " .find( " python " )

Output:

9

Indexing starts at 0 in Python. In the string ' learning python programming ' , the word ' python ' begins at index 9. Python’s built-in types documentation describes str.find() as returning the lowest index where the substring is found.

Therefore, the correct answer isB. 9.

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:.

The string method join() combines the strings in an iterable using the string before .join() as the separator.

In this question, the separator is an empty string:

' ' .join([ ' Hello ' , ' World ' ])

Because the separator is empty, Python joins ' Hello ' and ' World ' directly together with no space or comma between them.

Result:

' HelloWorld '

The official Python documentation defines str.join() as returning a string made by joining the strings in the given iterable.

Therefore, the correct answer is B. ' HelloWorld ' .

==========

Step 1: The function receives one string parameter named text.

Step 2: Since words are separated by spaces, use the .split() method to split the string into a list of words.

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

Step 4: Return that count.

Correct code:

def word_count(text):

return len(text.split())

Example:

print(word_count( " Hello world Python " ))

Output:

3

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.
