질문 # 25
Which components are required in every Python while loop?

정답：D

설명：
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.


질문 # 26
Which Python data structure cannot be modified after creation?

정답：D

설명：
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.


질문 # 27
Fix the missing return statement in this function that should return whether a number is even.
def is_even(number):
if number % 2 == 0:
True
else:
False

정답：

설명：
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The expression number % 2 == 0 checks whether the number is even.
Step 2: The original code writes True and False, but it does not return them.
Step 3: A function must use the return statement to send a value back to the caller.
Correct code:
def is_even(number):
if number % 2 == 0:
return True
else:
return False
Simplified correct code:
def is_even(number):
return number % 2 == 0
Example:
print(is_even(4))
print(is_even(7))
Output:
True
False


질문 # 28
Which punctuation mark must appear at the end of an if statement line?

정답：C

설명：
In Python, an if statement line must end with a colon.
Example:
age = 18
if age > = 18:
print( " Adult " )
The colon : tells Python that an indented block of code follows. That indented block contains the statements that should run when the condition is true.
A semicolon, period, or comma is not used to begin the body of an if statement in Python.
Therefore, the correct answer is B. : colon.


질문 # 29
A dictionary prices = { ' apple ' : 1.50, ' banana ' : 0.75, ' orange ' : 2.00} needs to have all values increased by
0.25. Which code correctly accomplishes this task?

정답：A

설명：
In Python, iterating directly over a dictionary gives itskeys. In this dictionary, the keys are:
' apple '
' banana '
' orange '
To update each price, the program can loop through each key and use that key to access and change the corresponding value.
Correct code:
prices = { ' apple ' : 1.50, ' banana ' : 0.75, ' orange ' : 2.00}
for item in prices:
prices[item] = prices[ item] + 0.25
print(prices)
Output:
{ ' apple ' : 1.75, ' banana ' : 1.0, ' orange ' : 2.25}
Option B is incorrect because value actually receives each dictionary key, not each dictionary value. Also, assigning to value would not update the dictionary.
Option C is incorrect because item is not defined, and the loop structure is invalid for this task.
