dog.py
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=age
def sit(self):
"""模拟小狗被命令时蹲下"""
print(self,name.title()+" is now sitting.")
def roll_over(self):
"""模拟小狗被命令时打滚"""
print(self.name.title()+"roll over!")
my_dog=Dog('willie',6)
print("My dog's name is "+my_dog.name.title()+".")
print("My dog is "+str(my_dog.age)+"years old.")
当我运行以上的代码时发生如下截图的错误，提示对象不接受参数，为什么？
