ElementTree is a Python built-in module that provides a simple and efficient API for parsing and creating XML data. It allows you to access and manipulate XML data in a very straightforward way, making it easy to write XML processing applications.

This statement is true because ElementTree is a module in the standard library of Python that provides an API for working with XML data. The module supports parsing XML from strings or files, creating XML trees from scratch or modifying existing ones, searching and iterating over XML elements, and writing XML data to strings or files.

Composition is an object-oriented design concept that models ahas-a relationship. In composition, a class known ascompositecontains an object of another class known ascomponent.In other words, a composite class has a component of another class1.

1. 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.

Option A is true because PEP 8 recommends avoiding extraneous whitespace immediately inside parentheses, brackets or braces1.

Option C is true because PEP 8 recommends avoiding extraneous whitespace between a trailing comma and a following close parenthesis1.

The correct answers areB. Option BandD. 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 theprintfunction 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.

The@propertydecorator should be defined after the method that is responsible for setting an encapsulated attribute is a false sentence. In fact, the@propertydecorator should be defined before the method that is used to set the attribute value. The@propertydecorator and the setter and deleter methods work together to create an encapsulated attribute, which is used to provide control over the attribute's value.

Official Python documentation on Property:https://docs.python.org/3/library/functions.html#property

The@propertydecorator is used to designate a method as a getter for an instance attribute. The method decorated with@propertyshould be defined before any setter or deleter methods for the same attribute.
