Python:

Craps is a dice-based game played in many casinos. Like blackjack, a player plays against the house. The game starts with the player throwing a pair of standard, six-sided dice. If the player rolls a total of 7 or 11, the player wins. If the player rolls a total of 2, 3, or 12, the player loses. For all other roll values, the player will repeatedly roll the pair of dice until either she/he rolls the initial value again (in which case she/he wins) or 7 (in which case she/he loses). Develop a classCrapsthat uses the Die class developed above to simulate a game of craps. The class should be a subclass of the object class, not Die. The class supports two methods:

__init__() which takes no parameters. It creates two six-sided Die objects and stores them into two variables in the object. It then stores the sum of the initial rolls of the two dice into a variable in the class representing the initial roll of the player. If the initial roll is 7 or 11, the constructor reports that the player wins. If the initial roll is 2, 3, or 12, the constructor reports that the player loses. If the initial roll is any other value the constructor suggests that the player throw for point.

forPoint() which takes no parameters and rolls the next round of the craps game. If the player rolls a 7, the method reports that the player lost. If the player rolls the same value as the initial roll, the method reports that the player wins. Otherwise the method suggests that the player again roll for point.

The following shows how the Craps class and methods could be used. Note that the situation where the user immediately loses is not represented although you have to handle that case in your implementation
