질문 # 52
Analyze the following snippet and select the statement that best describes it.

A. The code is syntactically correct despite the fact that the names of the function parameters do not follow the naming convention
B. The code is missing a placeholder for unnamed parameters.
C. The *arg parameter holds a list of unnamed parameters
D. The code is syntactically incorrect - the function should be defined as def f1 (*args, **kwargs)

정답：C

설명：
Explanation
The provided code snippet defines a function f1 that accepts variable-length arguments using the *args and **kwargs syntax. The *args parameter allows for an arbitrary number of unnamed arguments to be passed to the function as a tuple, while the **kwargs parameter allows for an arbitrary number of named arguments to be passed to the function as a dictionary.
Therefore, the correct statement that best describes the code is:
The *args parameter holds a list of unnamed parameters, while the **kwargs parameter holds a dictionary of named parameters.

질문 # 53
Select the true statements about the connection-oriented and connectionless types of communication. (Select two answers.)

A. In the context of TCP/IP networks, the communication side that initiates a connection is called the client, whereas the side that answers the client is called the server
B. Using walkie-talkies is an example of a connection-oriented communication
C. A phone call is an example of a connection-oriented communication
D. Connectionless communications are usually built on top of TCP

정답：A,C

설명：
Explanation
In the context of TCP/IP networks, the communication side that initiates a connection is called the client, whereas the side that answers the client is called the server.
This statement is true because TCP/IP networks use a client-server model to establish connection-oriented communications. The client is the device or application that requests a service or resource from another device or application, which is called the server. The server responds to the client's request and provides the service or resource.For example, when you browse a website using a web browser, the browser acts as a client and sends a request to the web server that hosts the website. The web server acts as a server and sends back the requested web page to the browser1.
Connectionless communications are usually built on top of TCP.
This statement is false because TCP (Transmission Control Protocol) is a connection-oriented protocol that requires establishing and terminating a connection before and after sending data. Connectionless communications are usually built on top of UDP (User Datagram Protocol), which is a connectionless protocol that does not require any connection setup or teardown. UDP simply sends data packets to the destination without checking if they are received or not2.
Using walkie-talkies is an example of a connection-oriented communication.
This statement is false because using walkie-talkies is an example of a connectionless communication.
Walkie-talkies do not establish a dedicated channel or connection between the sender and receiver before transmitting data. They simply broadcast data over a shared frequency without ensuring that the receiver is ready or available to receive it. The sender does not know if the receiver has received the data or not3.
A phone call is an example of a connection-oriented communication.
This statement is true because a phone call is an example of a connection-oriented communication. A phone call requires setting up a circuit or connection between the caller and callee before exchanging voice data. The caller and callee can hear each other's voice and know if they are connected or not. The phone call also requires terminating the connection when the conversation is over4.

https://en.wikipedia.org/wiki/Walkie-talkie 4: https://en.wikipedia.org/wiki/Telephone_call A is true because in the context of TCP/IP networks, the communication side that initiates a connection is called the client, and the side that answers the client is called the server. This is the basis for establishing a connection-oriented communication.
D is true because a phone call is an example of a connection-oriented communication. Like TCP/IP, a phone call establishes a connection between two devices (in this case, two phones) before communication can occur.
A is true because in the context of TCP/IP networks, the communication side that initiates a connection is called the client, and the side that answers the client is called the server. This is the basis for establishing a connection-oriented communication.
D is true because a phone call is an example of a connection-oriented communication. Like TCP/IP, a phone call establishes a connection between two devices (in this case, two phones) before communication can occur.
B is false because connectionless communications are usually built on top of UDP, not TCP. UDP is a connectionless protocol that does not establish a connection before sending data.
C is false because using walkie-talkies is an example of a connectionless communication. Walkie-talkies do not establish a connection before communication begins, and messages are simply broadcasted to all devices within range.
Here is a sample code in Python using the socket module to create a TCP server and client to demonstrate the connection-oriented communication:
Server-side code:
importsocket
HOST ='127.0.0.1'
PORT =8080
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.bind((HOST, PORT))
s.listen()
conn, addr = s.accept()
with conn:
print('Connected by', addr)
whileTrue:
data = conn.recv(1024)
ifnotdata:
break
conn.sendall(data)
Client-side code:
importsocket
HOST ='127.0.0.1'
PORT =8080
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.connect((HOST, PORT))
s.sendall(b'Hello, world')
data = s.recv(1024)
print('Received',repr(data))
The server listens for incoming connections on port 8080, and when a connection is established, it prints the address of the client that has connected. The server then continuously receives data from the client and sends it back to the client until the connection is closed.
The client establishes a connection with the server and sends the message "Hello, world" encoded as bytes. It then waits for a response from the server and prints the data it receives.

질문 # 54
Select the true statements about the sqirte3 module. (Select two answers.)

A. The special name memory is used to create a database in RAM.
B. The sqhte3 module does not support transactions.
C. The sqlite3 module provides an interface compliant with the DB-API 2.0.
D. The fetchall method returns an empty list when no rows are available

정답：A,C

설명：
A). The sqlite3 module in python provides an interface compliant to the DB-API 2.0. Thus, it follows a standard performance metric that allows for consistency in database programming with python.
B). The special name 'memory' is used to create a database in RAM using the sqlite3 module. Thus, when you use it as the name of the database file while opening a connection, it creates a temporary database that exists only in memory.
Reference: Official Python documentation on sqlite3: https://docs.python.org/3/library/sqlite3.html

질문 # 55
Which of the following constants will be used if you do riot define the quoting argument in the writer method provided by the csv module?

A. csv.QUOTE_NONE
B. csv.QUOTE_NONNUMERIC
C. csv.QUOTE_MINIMAL
D. svQUOTE_ALL

정답：C

설명：
If you do not define the quoting argument in the writer method provided by the csv module, the default quoting behavior is set to QUOTE_MINIMAL. This means that fields containing special characters such as the delimiter or newline character will be quoted, while fields that do not contain special characters will not be quoted.
Reference: Official Python documentation on the csv module: https://docs.python.org/3/library/csv.html

질문 # 56
Select the true statements related to PEP 8 programming recommendations for code writing. (Select two answers:)

A. You should not write string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them
B. You should use the not ... is operator (e.g. if not spam is None:), rather than the is not operator (e.g. if spam is not None:), to increase readability.
C. You should write code in a way that favors the CPython implementation over PyPy, Cython. and Jython.
D. You should make object type comparisons using the ismstanceQ method (e.g. if isinstance (obj, int) :) instead of comparing types directly (eg if type(obj) is type(i)).

정답：A,D

설명：
The two true statements related to PEP 8 programming recommendations for code writing are Option B and Option D .
Option B is true because PEP 8 recommends making object type comparisons using the isinstance() method instead of comparing types directly 1 .
Option D is true because PEP 8 recommends not writing string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them 1 .
