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…
PLEASE CODE IN PYTHON PLEASE USE NESTED CLASS FUNCTION Design a Point Class with attributes X and Y coordinates. The Class should have following functions: a) change the coordinates, b) return a 2 element list [x,y] c) print a Point object. d) return distance from this instance to a given [x,y] Also design a Line Class which has 2 Point attributes. The Line class should have functions for following behaviours: a) Return the length of the line. b) Print the equation of the line c) Find if this instance is equal in length to another line.

Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.
