The code is responsible for the support of the inequality operator i.e. i != j. In the given code snippet, the __ne__ method is a special method that overrides the behavior of the inequality operator != for instances of the MyClass class. When the inequality operator is used to compare two instances of MyClass, the __ne__ method is called to determine whether the two instances are unequal.QUESTION 27Analyze the following snippet and select the statement that best describes it.  The code is an example of implicitly chained exceptions.  The code is erroneous as the OwnMath class does not inherit from any Exception type class  The code is fine and the script execution is not interrupted by any exception.  The code is an example of explicitly chained exceptions. ExplanationIn the given code snippet, an instance of OwnMath exception is raised with an explicitly specified __cause__ attribute that refers to the original exception (ZeroDivisionError). This is an example of explicitly chaining exceptions in Python.QUESTION 28Select the true statement related to PEP 257.  String literals that occur immediately after another docstring are called attribute docstrings.  Attribute docstrings and Additional docstrings are two types of extra docstrings that can be extracted by software tools.  String Iiterals that occur in places other than the first statement in a module, function, or class definition can act as documentation They are recognized by the Python bytecode compiler and are accessible as runtime object attributes  String literals that occur immediately after a simple assignment at the top level of a module are called complementary docstrings ExplanationThe true statement related to PEP 257 is Option B. According to PEP 257, string literals occurring elsewhere in Python code may also act as documentation. They are not recognized by the Python bytecode compiler and are not accessible as runtime object attributes (i.e. not assigned to doc), but two types of extra docstrings may be extracted by software tools: String literals occurring immediately after a simple assignment at the top level of a module, class, or init method are called “attribute docstrings”. String literals occurring immediately after another docstring are called “additional docstrings”1.QUESTION 29Select the true statement about composition  Composition extends a class’s capabilities by adding new components and modifying the existing ones.  Composition allows a class to be projected as a container of different classes  Composition is a concept that promotes code reusability while inheritance promotes encapsulation.  Composition is based on the has a relation: so it cannot be used together with inheritance. ExplanationComposition 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 class1. 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.References:* Official Python documentation onComposition: https://docs.python.org/3/tutorial/classes.html#composition* GeeksforGeeks article on Composition vsInheritance: https://www.geeksforgeeks.org/composition-vs-inheritance-python/* Real Python article on Composition andInheritance: https://realpython.com/inheritance-composition-python/QUESTION 30Select the true statement about the socket. gaierror exception.  It is raised when an address-related error caused by the repr () function occurs.  It is raised when an address-related error caused by the getaddrinfo () and getnameinfo () functions occurs.  It is raised when a system function returns a system-related error.  It is raised when a timeout occurs on a socket. ExplanationThe socket.gaierror exception is raised when an address-related error caused by the getaddrinfo() and getnameinfo() functions occurs. These functions are used to translate hostnames to IP addresses and vice versa, and the gaierror exception is raised if they fail to perform this translation.QUESTION 31Select the true statements about the sqlite3 module. (Select two answers.)  The fetchalt method returns None when no rows are available  The execute method allows you to perform several queries at once  The execute method is provided by the Cursor class  The fetchone method returns None when no rows are available Explanation The execute method is provided by the Cursor classThis statement is true because the execute method is one of the methods of the Cursor class in the sqlite3 module. The Cursor class represents an object that can execute SQL statements and fetch results from a database connection. The execute method takes an SQL query as an argument and executes it against the database. For example, cur = conn.cursor (); cur.execute (“SELECT * FROM table”) creates and executes a cursor object that selects all rows from a table. The fetchone method returns None when no rows are availableThis statement is true because the fetchone method is another method of the Cursor class in the sqlite3 module.The fetchone method fetches the next row of a query result set and returns it as a single tuple or None if no more rows are available. For example, row = cur.fetchone () fetches and returns one row from the cursor object or None if there are no more rows.QUESTION 32Select the true statements about the json.-dumps () function. (Select two answers.)  It returns a JSON string.  It returns a Python entity.  It takes a JSON string as its argument  It takes Python data as its argument. ExplanationThe 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.QUESTION 33A socket object is usually created by which one of the following invocations?  socket. socket (socket_domain, socket_type)  socket = socket. socket (socket_number)  socket = socket. socket (socket_domain, socket_type, server_address)  socket = socket.socket(server address) ExplanationA socket object is usually created using the socket() constructor provided by the socket module in Python. The correct invocation is socket.socket(socket_domain, socket_type). This creates a new socket object with the specified socket domain and type.QUESTION 34What is true about the invocation of the cget () method?  It can be used to read widget attributes.  It has the same effect as the config () method.  It can be used to set new values to widget attributes.  It can be replaced with a dictionary-like access manner. ExplanationThe cget() method in Python is used to read the configuration options of a widget in Tkinter. It retrieves the value of a specified configuration option for a Tkinter widget. Hence, option A is the correct answer.QUESTION 35Select the true statements related to PEP 8 programming recommendations for code writing. (Select two answers:)  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 notNone:), to increase readability.  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)).  You should write code in a way that favors the CPython implementation over PyPy, Cython. and Jython.  You should not write string literals that rely on significant trailing whitespaces as they may be visually indistinguishable, and certain editors may trim them ExplanationThe 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.QUESTION 36What will be the content of the co/ors.csv filewhen you run the following code?A)B)C)D)An exception will be raised.  Option A  Option B  Option C  Option D QUESTION 37Look at the following code snippets and decide which ones follow PEP 8 recommendations for whitespacesin expressions and statements(Select two answers.)  No whitespace immediately before the opening parenthesis that starts the list of arguments of a function call:  A whitespace immediately before a comma,semicolon, and colon:  No whitespace between a trailing comma and a following closing parenthesis:  A whitespace immediately after the opening parenthesis that starts indexing or slicing: ExplanationOption A is true because PEP 8 recommends avoiding extraneous whitespace immediately inside parentheses, brackets or braces 1.Option C is true because PEP 8 recommends avoiding extraneous whitespace between a trailing comma and a following close parenthesis 1.QUESTION 38What does the term deserialization mean? Select the best answer.  It is a process of creating Python objects based on sequences of bytes.  It is a process of assigning unique identifiers to every newly created Python object  It is another name for the data transmission process  It is a process of converting the structure of an object into a stream of bytes Explanationanswer A. Deserialization is the process of converting data that has been serialized or encoded in a specific format, back into its original form as an object or a data structure in memory. In Python, this typically involves creating Python objects based on sequences of bytes that have been serialized using a protocol such as JSON, Pickle, or YAML.For example, if you have a Python object my_obj and you want to serialize it to a JSON string, you might do something like this:importjsonserialized_obj = json.dumps(my_obj)To deserialize the JSON string back into a Python object, you would use the json.loads() method:deserialized_obj = json.loads(serialized_obj)This would convert the JSON string back into its original Python object form.QUESTION 39Which sentence about the property decorator is false?  The property decorator should be defined after the method that is responsible for setting an encapsulated attribute.  The @property decorator designates a method which is responsible for returning an attribute value  The property decorator marks the method whose name will be used as the name of the instance attribute  The property decorator should be defined before the methods that are responsible for setting and deleting an encapsulated attribute ExplanationThe @property decorator should be defined after the method that is responsible for setting an encapsulated attribute is a false sentence. In fact, the @property decorator should be defined before the method that is used to set the attribute value. The @property decorator and the setter and deleter methods work together to create an encapsulated attribute, which is used to provide control over the attribute’s value.QUESTION 40The following snippet represents one of the OOP pillars Which one is that?  Serialization  Inheritance  Encapsulation  Polymorphism ExplanationThe given code snippet demonstrates the concept of encapsulation in object-oriented programming.Encapsulation refers to the practice of keeping the internal state and behavior of an object hidden from the outside world and providing a public interface for interacting with the object. In the given code snippet, the __init__ and get_balance methods provide a public interface for interacting with instances of the BankAccount class, while the __balance attribute is kept hidden from the outside world by using a double underscore prefix. Loading … Verified & Correct PCPP-32-101 Practice Test Reliable Source May 13, 2023 Updated: https://www.validbraindumps.com/PCPP-32-101-exam-prep.html --------------------------------------------------- Images: https://free.validbraindumps.com/wp-content/plugins/watu/loading.gif https://free.validbraindumps.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2023-05-13 13:47:34 Post date GMT: 2023-05-13 13:47:34 Post modified date: 2023-05-13 13:47:34 Post modified date GMT: 2023-05-13 13:47:34
