질문 # 51
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]

정답：

설명：
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

질문 # 52
What must a developer do to run Python code written in a text editor?

A. Press a run button within the editor.
B. Convert the code to machine language first.
C. Save the file and use a Python interpreter.
D. Upload the code to a web server.

정답：C

설명：
When Python code is written in a text editor, the developer should save the file, usually with a .py extension, and run it using the Python interpreter.
Example terminal command:
python script.py
Python's documentation explains that a Python module is a file containing Python definitions and statements, usually saved with the .py suffix.
Therefore, the correct answer isA. Save the file and use a Python interpreter.

질문 # 53
Which Python data structure allows duplicate values and supports methods like append() and remove()?

A. Tuple
B. List
C. Set
D. Dictionary

정답：B

설명：
A list is a Python data structure that can store multiple values. Lists can contain duplicate values, and they support methods such as append() and remove().
Example:
fruits = [ " apple " , " banana " , " apple " ]
fruits.append( " orange " )
fruits.remove( " banana " )
print(fruits)
Output:
[ ' apple ' , ' apple ' , ' orange ' ]
The value " apple " appears more than once, showing that lists allow duplicates.
The official Python documentation lists list.append() as a method that adds an item to the end of a list and list.
remove() as a method that removes the first matching value from a list.
Therefore, the correct answer is C. List.

질문 # 54
In the code for item in my_list:, what does item represent?

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

정답：D

질문 # 55
Which type of loop repeatedly checks a condition to determine whether to continue?

A. for loop
B. while loop
C. range loop
D. repeat loop

정답：B

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 # 56
