    class hayvan():
    def __init__(self,habitat,beslenmetur,solunumtur,sinif,bireysayisi,avlar=["Fare"],avcilar=["Yılan"]):
        self.habitat=habitat
        self.beslenmetur=beslenmetur
        self.solunumtur=solunumtur
        self.sinif=sinif
        self.bireysayisi=bireysayisi
        **self.avlar=avlar
        self.avcilar=avcilar**
    def __str__(self):
        return "Hayvan Classı Calıstı"
    def __len__(self):
        return bireysayisi
    def avekle(self,yeniav):
        self.avlar.append(yeniav)
    def avciekle(self,yeniavci):
        self.avcilar.append(yeniavci)
    class kopek(hayvan):
    def __init__(self,cins,kullanimalani,karakteristikozellik,habitat,beslenmetur,solunumtur,sinif,bireysayisi,avlar=[],avcilar=[]):
        super().__init__(habitat,beslenmetur,solunumtur,sinif,bireysayisi,avlar=[],avcilar=[])
        self.cins=cins
        self.kullanimalani=kullanimalani
        self.karakteristikozellik=karakteristikozellik
    def ozellikekle(self,yeniozellik):
        self.karakteristikozellik.append(yeniozellik)
    def showinfos(self):
        print("Cins: {}\nKullanım Alanı: {}\nKarakteristik Oz. : {}\nHabitat: {}\nBeslenme/Solunum Tur: {}/{}\nSınıf: {}\nBirey Sayısı: {}\nAvlar/Avcılar: {}/{}".format(self.cins,self.kullanimalani,self.karakteristikozellik,self.habitat,self.beslenmetur,self.solunumtur,self.sinif,self.bireysayisi,self.avlar,self.avcilar))

golden=kopek("golden","zenginlik","sadık","bahçeliev","etcil","akciger","omurgalı",1,"","")
golden.avekle("fare")
golden.avekle("güvercin")
golden.avciekle("yılan")
golden.avciekle("akrep")
golden.ozellikekle("koruyucu")
golden.showinfos()

ı meant to add a new membre to list.
