질문 # 39
Which tool is used to execute Python code line-by-line interactively within a terminal?
정답：D
설명：
The Python shell allows Python code to be entered and executed interactively, one line at a time.
Example:
> > > 2 + 3
5
Python's documentation explains that when commands are read from a terminal, the interpreter is in interactive mode and prompts for the next command.
Therefore, the correct answer isA. Python shell.
질문 # 40
Which terminal command is used to navigate to a different directory before running a Python script?
정답：C
설명：
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.
질문 # 41
Which type of loop repeatedly checks a condition to determine whether to continue?
정답：A
설명：
Awhile looprepeatedly executes a block of code as long as its condition remains true.
Example:
count = 1
while count < = 3:
print(count)
count += 1
In this example, Python checks the condition count < = 3 before each loop iteration. If the condition is true, the loop continues. When the condition becomes false, the loop stops.
A for loop is usually used to iterate over a sequence, such as a list, string, or range. Python does not have a built-in repeat loop construct.
Therefore, the correct answer isB. while loop.
질문 # 42
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}.
정답：C
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 # 43
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.
