オブジェクト指向　Python 継承

Pyhonによるオブジェクト指向プログラミングのサンプルプログラムです

継承の目的

継承とインスタンス化（inheritance）

基底クラスを継承してクラスを作ると両方のメソッドが使える

事例

継承

オーバーライド（上書き）

ソースコード

カラー表示用のクラス

基底クラス

人間のクラスを作成します。

class Human():
    name = "Human"
    attribute = "Human"
    cWalk = 20 ; sWalk = "."
    tColor = Color.WHITE ; rColor = Color.RESET
    
    def __init__(self, n ): 
        self.name = n

    def Walk(self): 
        s = ""
        for i in range(self.cWalk):
            s += self.sWalk
        print(self.attribute,self.tColor,s,"(",self.name,")",self.rColor)

    def Run(self): 
        s = ""
        for i in range(self.cWalk):
               s += self.sWalk+self.sWalk
        print(self.attribute,self.tColor,s,"(",self.name,")",self.rColor)

盾の戦士　クラス　

基底クラスを継承した。サブクラスを作成します。

class Shielder(Human):
    name = "Shielder"
    attribute = "Shielder"
    tColor = Color.RED ; rColor = Color.RESET
    cshield = 5 ; sshield = "@"
 
    def __init__(self, n ): 
        self.name = n

    def Defense(self):
        s = ""
        for i in range(self.cshield): 
            s += self.sshield
        print(self.attribute,self.tColor, s, "(" , self.name, ")", self.rColor )
    
    def Attack(self):
        s = ""
        for i in range(self.cshield): 
            s += self.sshield
        print(self.attribute,self.tColor, s, "(" , self.name, ")", self.rColor )

魔法の戦士　クラス　（人間クラスを継承）

class Wizard(Human):
    name = "Wizard"
    attribute = "Wizard"
    tColor = Color.GREEN ; rColor = Color.RESET
    cshield = 20 ; sshield = "~"
 
    def __init__(self, n ): 
        self.name = n

    def Defense(self):
        s = ""
        for i in range(self.cshield): 
            s += self.sshield
        print(self.attribute,self.tColor, s, "(" , self.name, ")", self.rColor )
    
    def Attack(self):
        s = ""
        for i in range(self.cshield): 
            s += self.sshield
        print(self.attribute,self.tColor, s, "(" , self.name, ")", self.rColor )

メインクラス

class subMain:
    # humanList = ["Nao*","Itsu*","Moto*","Re*"]
    # hu = dict()
    s = Shielder( "Itsu*" )
    w = Wizard( "Moto*" )

    s.Defense()
    w.Attack()
    
if __name__ == "__main__":
    root = subMain()
