求python大佬看看，这代码哪里错了，照着书上敲得

class Person:
def init(self, name, age):
self.name = name
self.age = age
def detail(self):
print (self.name)
print(self.age)

obj1 = Person('santos', 18)

obj1.detail()
obj1.detail(obj1)

显示这个错误：改了半天没反应
TypeError Traceback (most recent call last)
in
7 print(self.age)
8
----> 9 obj1 = Person('santos', 18)
10 obj1.detail()
11 obj1.detail(obj1)

TypeError: object() takes no parameters

obj1.detail(obj1)去掉
因为detail的self参数就是obj1，没有别的参数了
