为什么说:'Klasa' object has no attribute 'ispisi?当 ispisi 是我要调用的方法时

Why does it says: 'Klasa' object has no attribute 'ispisi? When ispisi is method that I am trying to call

class Klasa:
   def __init__(self,x,y):
    self.x = x
    self.y = y

    def oduzmi(self,x,y):
        return  x - y

    def ispisi(self):
        print('rezultat je: ', self.oduzmi(self.x,self.y))

klasa = Klasa(2,3)
klasa.ispisi()

如果您使用 vscode,请检查缩进我建议您检查 Indentation in VS Code

class Klasa:
    def __init__(self,x,y):
        self.x = x
        self.y = y

    def oduzmi(self,x,y):
        return  x - y

    def ispisi(self):
        print('rezultat je: ', self.oduzmi(self.x,self.y))

klasa = Klasa(2,3)
klasa.ispisi()
