질문 # 40
What distinguishes a terminal-based Python environment from other development environments?
정답：C
설명：
A terminal-based Python environment uses atext-based command line interface. In this environment, the user types commands directly into a terminal or command prompt.
For example, a user may start Python by typing:
python
When Python is started from a terminal, the interpreter can run in interactive mode, where it displays prompts such as > > > and waits for the user to enter Python commands. The official Python documentation explains that when commands are read from a terminal, the interpreter is in interactive mode.
A terminal-based environment is not mainly identified by graphical user interface elements, internet connectivity, or automatic file saving.
Therefore, the correct answer isC. Text-based command line interface.
질문 # 41
Which action allows a Python script located in a different folder to be executed in the terminal?
정답：B
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 # 42
Which punctuation mark must appear at the end of an if statement line?
정답：B
설명：
In Python, an if statement line must end with a colon.
Example:
age = 18
if age > = 18:
print( " Adult " )
The colon : tells Python that an indented block of code follows. That indented block contains the statements that should run when the condition is true.
A semicolon, period, or comma is not used to begin the body of an if statement in Python.
Therefore, the correct answer is B. : colon.
질문 # 43
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
정답：
설명：
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
질문 # 44
Complete the function add_item(numeric_list, new_number) that takes a list of numbers and a new number, and returns a new list that appends the new number to the end of the list.
For example, add_item([1, 2, 3], 4) should return [1, 2, 3, 4] .
정답：A
설명：
The correct function uses the list method append() to add new_number to the end of numeric_list.
Correct code:
def add_item(numeric_list, new_number):
numeric_list.append(new_number)
return numeric_list
Example:
add_item([1, 2, 3], 4)
Result:
[1, 2, 3, 4]
Python's data structures documentation explains that list.append(x) adds an item to the end of the list.
Therefore, the correct answer isA.
