python怎么提示给了四个参数

Question

这不明明只有三个为啥提示给了四个参数然后报错了

class people:
    name=''
    age=0
    weight=100
    def __init__(self,name,age):
        self.name=name
        self.age=age
class student(people):
    grade=0
    def __int__(self,name,age,grade):
        people.__init__(self,name,age)
        self.grade=100
stu=student('a',10,100)
print(stu.name,stu.age,stu.grade)

stu=student('a',10,100)

TypeError: init() takes 3 positional arguments but 4 were given

Answer 1

图示位置敲错>_>

__init__
