[小白Python学习错题集]TypeError: Dog() takes no arguments

python小白

初学,学到第九章类，明明按照书上代码码入，却碰到如下问题w

class Dog:
    """一次模拟小狗的简单尝试"""

    def __int__(self,name,age):
        """初始化属性name和 age"""
        self.name = name
        self.age = str(age)

    def sit(self):
        """模拟小狗收到命令后坐下"""
        print(f"{self.name} is now sitting.")

    def roll_over(self):
        """模拟小狗收到命令坐下"""
        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.")

至于网站多数帖子说的 __init__左右两侧两个下划线的问题，书中有重点提，也注意了

但是确认两下划线问题后还是有问题

最后百思不得其解时发现竟然是int写错了，汗。。。。

修改后

class Dog:
    """一次模拟小狗的简单尝试"""

    def __init__(self,name,age):
        """初始化属性name和 age"""
        self.name = name
        self.age = str(age)

    def sit(self):
        """模拟小狗收到命令后坐下"""
        print(f"{self.name} is now sitting.")

    def roll_over(self):
        """模拟小狗收到命令坐下"""
        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.")
