WGU Foundations of Programming (Python) - E010 JIV1 認定 Foundations-of-Programming-Python 試験問題 (Q12-Q17):

質問 # 12
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?

正解:A

解説:
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.


質問 # 13
In Python, what must follow the in keyword in a for loop?

正解:C

解説:
In a Python for loop, the in keyword is followed by an iterable object, such as a list, string, tuple, dictionary, set, or range() object.
Example:
for name in [ " Alice " , " Bob " , " Carol " ]:
print(name)
Here, [ " Alice " , " Bob " , " Carol " ] is the iterable object. Python's documentation explains that a for statement iterates over the items of a sequence or other iterable object.
Therefore, the correct answer isB. An iterable object.


質問 # 14
How can the first four characters be extracted from the string ' computer ' ?

正解:C

解説:
Python strings are sequences, and sequence values can be accessed using indexing and slicing.
The first character in a Python string has index 0. To extract the first four characters from ' computer ' , the slice should start at index 0 and stop at index 4.
Example:
' computer ' [0:4]
Result:
' comp '
In Python slicing, the start index is included, but the stop index is excluded. So [0:4] includes characters at indexes 0, 1, 2, and 3.
The official Python documentation explains that slicing with a[start:stop] selects items from the start index up to, but not including, the stop index.
Therefore, the correct answer is A. ' computer ' [0:4].


質問 # 15
Which Python data structure contains only unique elements and does not support indexing?

正解:A

解説:
A set is a Python data structure that stores only unique elements. This means duplicate values are automatically removed.
Example:
numbers = {1, 2, 2, 3}
print(numbers)
Output:
{1, 2, 3}
The duplicate value 2 appears only once in the set.
Sets are also unordered, so they do not support indexing like lists or tuples do. For example, numbers[0] would cause an error because sets are not accessed by position.
The official Python documentation describes sets as unordered collections with no duplicate elements.
Therefore, the correct answer is D. Set.


質問 # 16
In the code for item in my_list:, what does item represent?

正解:B
