一直在报错 实在不知道什么原因了，init我开头和末尾都输入两个下划线了
class Dog:def__init__(self,name,age):
self.name = name
self.age = age
def sit(self):
print(f"{self.name}is now sitting.")
def roll_over(self):
print(f"{self.name}rolled over!")
my_dog = =Dog('willie',6)
print(f"My dog's name is {my_dog.name}.")
print(f"My dog is {my_dog.age} years old.")
class Dog:
def __init__(self,name,age):#def 和__init__要有空格
self.name = name
self.age = age
def sit(self):
print(f"{self.name}is now sitting.")
def roll_over(self):
print(f"{self.name}rolled over!")
my_dog=Dog('willie',6)#这是实例化对象一个等号就行
print(f"My dog's name is {my_dog.name}.")
print(f"My dog is {my_dog.age} years old.") 小伤口 发表于 2021-1-9 11:29
