Answer : A

The correct Python for loop syntax uses the keyword in.

Correct code:

for name in ['Alice', 'Bob', 'Carol']:

print(name)

This loop processes each name in the list one at a time. Python's documentation explains that a for statement iterates over the items of a sequence or iterable.

Therefore, the correct answer isA. for name in ['Alice', 'Bob', 'Carol']:.

Answer : B

The break keyword exits a loop immediately before the loop condition naturally becomes false or before all items have been processed.

Example:

for number in range(10):

if number == 5:

break

print(number)

When number becomes 5, the loop stops. Python's control-flow documentation explains the use of break in loops.

Therefore, the correct answer isB. break.

Answer : A

==========

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

Answer : A

==========

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

Answer : C

Atupleis immutable, which means it cannot be changed after it is created.

Example:

coordinates = (10, 20)

After this tuple is created, its elements cannot be modified directly. Python's data model documentation explains that tuples are immutable, while lists and dictionaries are mutable.

Therefore, the correct answer isC. Tuple.
