질문 # 19
Select the correct statements about the csv module.
(Select two answers.)
정답：A,B
설명：
The correct answers are B and D. In Python's csv module, a normal csv.reader object reads each CSV row as a list of strings, so option B is true. A csv.DictReader object reads each row into a dictionary, using field names as keys, so option D is also true. Option A is false because DictReader does not always take headers from the first row; field names can be provided explicitly through the fieldnames argument. Option C is false because DictWriter requires field names so it knows which dictionary keys correspond to CSV columns and in what order they should be written. This distinction between row lists and row dictionaries is central to CSV processing.
질문 # 20
Select the true statement about composition
정답：A
설명：
Composition is an object-oriented design concept that models a has-a relationship . In composition, a class known as composite contains an object of another class known as component . In other words, a composite class has a component of another class 1 .
B). Composition allows a class to be projected as a container of different classes.
Composition is a concept in Python that allows for building complex objects out of simpler objects, by aggregating one or more objects of another class as attributes. The objects that are aggregated are generally considered to be parts of the whole object, and the containing object is often viewed as a container for the smaller objects.
In composition, objects are combined in a way that allows for greater flexibility and modifiability than what inheritance can offer. With composition, it is possible to create new objects by combining existing objects, by using a container object to host other objects. By contrast, with inheritance, new objects extend the behavior of their parent classes, and are limited by that inheritance hierarchy.

질문 # 21
Select the true statements about the following invocation:
(Select two answers.)
정답：A,C
설명：
Explanation
It addresses a service deployed at localhost (the host where the code is run).
This statement is true because localhost is a special hostname that refers to the local machine or the current host where the code is run. It is equivalent to using the IP address 127.0.0.1, which is the loopback address of the network interface. By using localhost as the hostname, the invocation addresses a service that is deployed on the same machine as the client.
It addresses a service listening at port 3000.
This statement is true because port 3000 is the part of the URL that follows the colon after the hostname. It specifies the port number where the service is listening for incoming requests. A port number is a 16-bit integer that identifies a specific process or application on a host. By using port 3000, the invocation addresses a service that is listening at that port.
It addresses a service whose timeout is set to 3000 ms.
This statement is false because timeout is not a part of the URL, but a parameter that can be passed to the requests.get () function in Python. Timeout specifies how long to wait for the server to send data before giving up. It is measured in seconds, not milliseconds. By using timeout=3, the invocation sets the timeout to 3 seconds, not 3000 ms.
It addresses a service located at the following address local.host.com.
This statement is false because local.host.com is not the same as localhost. Local.host.com is a fully qualified domain name (FQDN) that consists of three parts: local, host, and com. It requires DNS resolution to map it to an IP address. Localhost, on the other hand, is a special hostname that does not require DNS resolution and always maps to 127.0.0.1. By using localhost as the hostname, the invocation does not address a service located at local.host.com.

질문 # 22
Select the true statements about the json.-dumps () function. (Select two answers.)
정답：B,C
설명：
Explanation
The json.dumps() function is used to convert a Python object into a JSON string 1. It takes Python data as its argument, such as a dictionary or a list, and returns a JSON string.
질문 # 23
Select the true statement about the___name___attribute.
정답：B
설명：
The true statement about the __name__ attribute is D. name is a special attribute, which is inherent for classes, and it contains the name of a class . The __name__ attribute is a special attribute of classes that contains the name of the class as a string.
The __name__ attribute is a special attribute in Python that is available for all classes, and it contains the name of the class as a string. The __name__ attribute can be accessed from both the class and its instances using the dot notation.
