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.

==========

Step 1: In Python, the code inside a function must be indented.

Step 2: The return statement belongs inside the function body.

Step 3: Add indentation before the return statement.

Correct code:

def greet(name):

return " Hello " + name

Example:

print(greet( " Alice " ))

Output:

Hello Alice

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 parameter named number.

Step 2: The condition number > 0 checks whether the number is positive.

Step 3: In Python, this comparison already returns either True or False.

Correct code:

def is_positive(number):

return number > 0

Example:

print(is_positive(5))

print(is_positive(-2))

print(is_positive(0))

Output:

True

False

False

==========

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

==========

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 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

==========

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
