python 创建类时候总是报错

Question

class Dog():
def _init(self,name,age):
self.name=name
self.age=age

def sit(self):
     print(self.name.upper()+' is sitting .')
    
def run(self):                                                                                               （第九行）
     print(self.name.upper()+' is running .')

my_dog=Dog('kitty',9)
my_dog.run()

运行结果是第九行代码有问题
