질문 # 31
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}.

A. def update_grade(grades, student, new_grade):student = new_gradereturn student
B. def update_grade(grades, student, new_grade):grades.append(new_grade)return grades
C. def update_grade(grades, student, new_grade):pass
D. def update_grade(grades, student, new_grade):grades[student] = new_gradereturn grades

정답：D

설명：
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.

질문 # 32
In the code for item in my_list:, what does item represent?

A. The entire list
B. The current element being processed
C. The index of the current element
D. The length of the list

정답：B

질문 # 33
How can the first four characters be extracted from the string ' computer ' ?

A. ' computer ' [1:5]
B. ' computer ' [0:3]
C. ' computer ' [0:4]
D. ' computer ' [1:4]

정답：C

설명：
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].

질문 # 34
Which action allows a Python script located in a different folder to be executed in the terminal?

A. Use the cd command to navigate to the script ' s directory
B. Rename the script to match the terminal ' s path
C. Use the edit command to open the script first
D. Move the script to your desktop

정답：A

설명：
To run a Python script from the terminal, the terminal should be in the correct directory, or the full file path should be provided.
The cd command is commonly used to change directories before running the script.
Example:
cd Documents
python my_script.py
Python's documentation explains that Python can execute a script when the interpreter is called with a filename argument.
Therefore, the correct answer isC. Use the cd command to navigate to the script ' s directory.

질문 # 35
Complete the function get_second_item(items) that takes a list and returns the second item. Assume the input is always a list containing at least two elements.
For example, get_second_item([10, 20, 30]) should return 20.
def get_second_item(items):
# TODO: Return the second item from the list
pass

정답：

설명：
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: Python list indexing starts at 0.
Step 2: The first item is at index 0.
Step 3: The second item is at index 1.
Step 4: Return the value at index 1.
Correct code:
def get_second_item(items):
return items[1]
Example:
print(get_second_item([10, 20, 30]))
Output:
20
