Encapsulation:

• It combines the data and code into a single object.

• It helps in restricting access to the methods.

• This helps in preventing the data from being modified due to accident.

• The object’s variable is not directly accessible.

• Underscore helps in preventing the data from being accessed directly.

The encapsulation rules in Python can be summarized as follows:

Public method It is accessible from anywhere.
Public variables It can be accessed from anywhere.
Private method It can be accessed only in their own class
Private method It is accessible only in their class or method.

• It protects the data from tampering. By declaring the data field as private, direct modifications of properties are prevented.

• It makes the class easy to maintain and reduces the errors...

Transcribed Image Text 7-a) Danish works as a constructor. Like all constructors, he is also a beer fan. He likes beer so much that has K cups of beer daily. However, having more than K cups doesn't suit him, because the excess beer won't allow him to sleep at night. Danish's working day is divided into N periods. For every period, he knows how many kilobytes of weight he can lift. During each of the periods, Danish can either have or not to have one bottle of beer. If he is having a bottle of beer in some period, the amount of work in this period drops to zero. But he also gets a productivity boost, if he decides to skip beer during a period and the last bottle of beer, he had was no more than D periods ago, the amount of work during such a period is M times the usual.

Poker card in PythonLet the CarteBase class present itself in the context of this exercise. It encapsulates a game card characterized by numerical values for its face and its kind. The possible faces are integers from 1 to 13, with face 1 corresponding to the ace, and faces 11, 12 and 13 corresponding respectively to the jack, the queen and the king. The other faces are simply identified by their number from 2 to 10. The possible grades are integers from 1 to 4 corresponding respectively to the cards of spade, heart, tile and clover. Analyze this class to understand how it works. You are asked to create a class called CarteDePoker that inherits CarteBase and defines or redefines the following methods: force(self) which returns the strength of the card in the poker game. In Poker, cards have the strength of their digital face from 2 to 13, except for the ace which is stronger than the other cards. So we give it a strength of 14.__eq__(self, other) to define operator behavior…

These are about JS codes. Q1:Make a new object called "person". Give the person object 2 properties; * name * age name should be a string array, the first position holds your first name, and second your last. age should be a number, date * output the entire object to the console. /******************************************************************************* * Information: * * DOT NOTATION * * The object name (person) acts as the namespace â€” it must be entered first to access * anything inside the object. Next you write a dot, then the item you want to access * â€” this can be the name of a simple property, an item of an array property, or a call * to one of the object's methods. * * If you defined your object correctly in Q1, the following code should display your * name and age * ex: ********************************************************************************/ console.log(person.name); console.log(person.age); Q2: Redfine (recreate) your person…
