질문 # 24
Which keyword is used to exit a loop prematurely in Python?

정답:A

설명:
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.


질문 # 25
Which data type is the value 3.14 in Python?

정답:B

설명:
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.


질문 # 26
Fix the logic error in this function that should return the larger of two numbers.
def find_maximum(a, b):
if a < b:
return a
else:
return b

정답:

설명:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function should return the larger number.
Step 2: The condition a < b means b is larger than a.
Step 3: In the original code, when a < b is true, it incorrectly returns a.
Step 4: The return values need to be corrected.
Correct code:
def find_maximum(a, b):
if a < b:
return b
else:
return a
Alternative correct code:
def find_maximum(a, b):
if a > b:
return a
else:
return b
Example:
print(find_maximum(10, 20))
print(find_maximum(30, 15))
Output:
20
30


질문 # 27
A program uses this while loop to count down:
count = 5
while count > 0:
print(count)
Which issue is preventing the loop from working correctly?

정답:D

설명:
The loop condition is:
while count > 0:
At the start, count is 5, so the condition is true. The program prints the value of count.
However, inside the loop, the value of count is never changed. That means count always stays 5, so the condition count > 0 is always true. As a result, the loop runs forever.
A corrected version would be:
count = 5
while count > 0:
print(count)
count = count - 1
This decreases count by 1 during each loop iteration. Eventually, count becomes 0, and the condition count >
0 becomes false.
Therefore, the correct answer isB. It runs infinitely because count is never modified.


질문 # 28
A program needs to update all values in a list by adding 5 to each number. Which for loop structure accomplishes this task?

정답:B

설명:
To update the actual values inside a list, the program must update each value by itsindex.
The correct code is:
for i in range(len(numbers)):
numbers[i] = numbers[i] + 5
Here, range(len(numbers)) produces valid index positions for the list. The variable i is used to access and update each list element.
Example:
numbers = [10, 20, 30]
for i in range(len(numbers)):
numbers[i] = numbers[i] + 5
print(numbers)
Output:
[15, 25, 35]
Option A does not correctly update the original list:
for number in numbers:
number = number + 5
This changes only the temporary loop variable number, not the actual elements stored inside the list.
Therefore, the correct answer isB.
