WGU Foundations of Programming (Python) - E010 JIV1 認定 Foundations-of-Programming-Python 試験問題 (Q27-Q32):

質問 # 27
Complete the function update_grade(grades, student, new_grade) that takes a grades dictionary, a student name, and a new grade, then updates that student ' s grade and returns the dictionary.
For example, update_grade({ " Alice " : 85, " Bob " : 90}, " Alice " , 95) should return { " Alice " : 95, " Bob
" : 90}.

正解:D

解説:
A dictionary stores data as key-value pairs. In this function, the student name is the key, and the grade is the value.
Correct code:
def update_grade(grades, student, new_grade):
grades[student] = new_grade
return grades
Example:
update_grade({ " Alice " : 85, " Bob " : 90}, " Alice " , 95)
Result:
{ " Alice " : 95, " Bob " : 90}
Python's built-in types documentation includes dictionaries as mapping types, where values are accessed and updated using keys.
Therefore, the correct answer isA.


質問 # 28
Which terminal command is used to navigate to a different directory before running a Python script?

正解:D

解説:
The command cd means "change directory." It is used in a terminal to move from one folder to another.
Example:
cd Desktop
After navigating to the correct folder, a Python script can be run with a command such as:
python script.py
Therefore, the correct answer isC. cd.


質問 # 29
Fix the off-by-one error in this function that should return the first 3 characters of a string.
def first_three(text):
return text[0:2]

正解:

解説:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: Python string slicing uses this format:
text[start:stop]
Step 2: The start index is included.
Step 3: The stop index is excluded.
Step 4: To return the first 3 characters, start at index 0 and stop at index 3.
Correct code:
def first_three(text):
return text[0:3]
Simplified correct code:
def first_three(text):
return text[:3]
Example:
print(first_three( " Python " ))
Output:
Pyt


質問 # 30
Which Python data structure automatically prevents duplicate values from being stored?

正解:D

解説:
Asetstores only unique elements. If duplicate values are added, Python keeps only one copy.
Example:
numbers = {1, 2, 2, 3}
print(numbers)
Output:
{1, 2, 3}
Python's data structures documentation describes sets as collections with no duplicate elements.
Therefore, the correct answer isD. Set.


質問 # 31
Write a complete function word_count(text) that counts and returns the number of words in the given text.
Words are separated by spaces.
For example, word_count( " Hello world Python " ) should return 3.
def word_count(text):
# TODO: Count and return the number of words in text
pass

正解:

解説:
See the Step by Step Solution below in Explanation.
Explanation:
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
