Question

Python出现错误:builtins.TypeError: object() takes no parameters

# Easier to ask forgiveness (After)
class NegativeAgeError(Exception): # I can
pass # More powerful than break

class Person:
def __int__(self, name, age):
"""(Person, str, int) -> NoneType
Create a new person with the given name with the given name and age.
Age should be a non-negative integer
"""
self.name = name
if age < 0:
raise NegativeAgeError
else:
self.age = age

# Look before leaping

def make_person(age):
if age < 0:
return None
elif age > 200:
return None
else:
return Person('a', age)

当我输入
make_person(20)的时候，他说：

Traceback (most recent call last):
File "/Applications/Wing101.app/Contents/Resources/src/debug/tserver/_sandbox.py", line 1, in <module>
# Used internally for debug sandbox under external interpreter
File "/Applications/Wing101.app/Contents/Resources/src/debug/tserver/_sandbox.py", line 25, in make_person
builtins.TypeError: object() takes no parameters

求解～谢谢

__init__函数写错成__int__了：

class Person:    
    def __init__(self, name, age):        
        self.name = name        
        if age < 0:            
            raise NegativeAgeError        
        else:            
            self.age = age
        print self.name,self.age
    def make_person(self,age):      
        if age < 0:        
            return None    
        elif age > 200:        
            return None    
        else:        
            return Person('a', age)
test=Person('haha',20)
test.make_person(30)
