python面向對象應用案例——撲克牌發牌

 

遊戲介紹:  四名牌手打牌,電腦隨機將52張牌(不合大、小王)發給四名牌手,並在屏幕上顯示每位牌手的牌。app

程序設計步驟:三個類  Card類、Hand類和Poke類dom

Card類函數

Card類表明一張牌,其中,FaceNum字段指的是牌面數字1~13,Suit字段指的是花色,」梅」爲梅花,」方」爲方塊,」紅」爲紅桃,」黑」爲黑桃。ui

Card構造函數根據參數初始化封裝的成員變量,實現牌面大小和花色的初始化,以及是否顯示牌面,默認True爲顯示牌的正面 spa

1,Card構造函數根據參數初始化封裝的成員變量,實現牌面大小和花色的初始化,以及是否顯示牌面,默認True爲顯示牌正面;設計

2,_str_()方法時用來輸出牌面大小和花色;blog

3,pic_order()方法獲取牌的順序號,牌面按梅花1~13,方塊14- 26,紅桃27-39,黑桃40- 52順序編號(未洗牌以前),也就是說,梅花2順序號爲2,方塊A順序號爲14,方塊K順序號爲26;繼承

4.flip()是翻牌方法,改變牌面是否顯示的屬性值。遊戲

 

Hand類ip

Hand類表明一個玩家手裏拿的牌,其中,cards列表變量存儲牌手手中的牌。能夠增長牌、清空手裏的牌、把一張牌給別的牌手等操做。

Poke類

Poke類表明一副牌,一副牌看做是有52張牌的牌手,繼承Hand類。因爲其中cards列表變量要存儲52張牌,並且要進行發牌、洗牌操做,因此增長 populate(self) 生成存儲了52張牌的一手牌,存儲在cards列表變量中random模塊shuffle() 洗牌deal( self., hands,per_hand=13)可完成發牌動做方法。
