What is true about type in the object-oriented programming sense?

It is the bottommost type that any object can inherit from.
It is a built-in method that allows enumeration of composite objects
It is the topmost type that any class can inherit from
It is an object used to instantiate a class

Answer(s): C

Explanation:

In Python, type is the built-in metaclass that serves as the base class for all new-style classes. All new-style classes in Python, including built-in types like int and str, are instances of the type metaclass and inherit from it.

What 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

Answer(s): A

Explanation:

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:
import json serialized_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.

Deserialization is the process of converting a sequence of bytes, such as a file or a network message, into a Python object. This is the opposite of serialization, which is the process of converting a Python object into a sequence of bytes for storage or transmission.

QUESTION: 15

What is a___traceback___?
(Select two answers )

An attribute owned by every exception object
A special method delivered by the traceback module to retrieve a full list of strings describing the traceback
An attribute that is added to every object when the traceback module is imported
An attribute that holds interesting information that is particularly useful when the programmer wants to store exception details in other objects

Answer(s): A,D

Explanation:

The correct answers are A. An attribute owned by every exception object and D. An attribute that holds interesting information that is particularly useful when the programmer wants to store exception details in other objects. A traceback is an attribute of an exception object that contains a stack trace representing the call stack at the point where the exception was raised. The traceback attribute holds information about the sequence of function calls that led to the exception, which can be useful for debugging and error reporting.

QUESTION: 16

Which of the following examples using line breaks and different indentation methods are compliant with PEP 8 recommendations? (Select two answers.)

Answer(s): B,D

Explanation:

The correct answers are B. Option B and D. Option D. Both options B and D are compliant with PEP 8 recommendations for line breaks and indentation. PEP 8 recommends using 4 spaces per indentation level and breaking lines before binary operators. In option B, the arguments to the print function are aligned with the opening delimiter, which is another acceptable way to format long lines according to PEP 8. In option D, the second line is indented by 4 spaces to distinguish it from the next logical line.
