问题描述
因此,首先,我知道这里已经有很多答案与此问题相关,但是我找不到适合我问题的正确答案.尝试创建对象时,我基本上只会遇到此错误.如果有任何答案,请多多指教.
So first of all, I know there is a bunch of answers here already relating this question, but I couldn't find the right one for my problem. When trying to create an object i basically just get this error. If any answers, thanks in advice.
这是我的代码:
class Human:
__name = None
__height = 0
def __init__(self, name, height):
self.__name = name
self.__height = height
def set_name(self, name):
self.__name = name
def get_name(self):
return self.__name
def set_height(self, height):
self.__height = height
def get_height(self):
return self.__height
def get_type(self):
print('Human')
def toString(self):
return '{} is {} cm tall.'.format(self.__name,
self.__height)
person = Human('Corey', 180)
推荐答案
最常见的原因:__init __()拼写错误
此错误的常见原因是 __ init __()方法的拼写错误,通常是因为忘记了两个下划线或下划线之一:
Most common cause: misspelled __init__()
The usual cause of this error is that the __init__() method has been misspelled, usually by forgetting one of the two leading or trailing underscores:
>>> class A:
def __init_(self, x, y):
self.x = x
self.y = y
>>> A(10, 20)
Traceback (most recent call last):
File "<pyshell#33>", line 1, in <module>
A(10, 20)
TypeError: object() takes no parameters
少见的常见原因:缩进
另一个原因是缩进错误,其中 __ init __()方法没有缩进类定义的内部:
Less common cause: mis-indentiation
The other cause is mis-indentation where the __init__() method is not indented to be inside of the class definition:
>>> class B:
"""Example class"""
>>> def __init__(self, p, q):
self.p = p
self.q = q
>>> B(30, 40)
Traceback (most recent call last):
File "<pyshell#41>", line 1, in <module>
B(30, 40)
TypeError: object() takes no parameters
