==========

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: 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

==========

Step 1: The function receives two parameters: bill and tip_percent.

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

Step 3: Multiply the bill amount by that decimal value.

Correct code:

def calculate_tip(bill, tip_percent):

return bill * tip_percent / 100

Example:

print(calculate_tip(50, 20))

Output:

10.0

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'.

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.
