我一直收到一个类型错误
提问于 2011-12-01 10:18:18
我在自学python类，当我运行我的代码时，我得到了以下错误：
class Critter(object):
"""A virtual pet"""
def _init_(self, name, mood):
print("A new critter has been born!!!!!")
self.name = name
self.__mood = mood
def talk(self):
print("\n Im",self.name)
print("Right now I feel",self._mood)
def _private_method(self):
print("this is a private method")
def public(self):
print("This is a public method. ")
self._private_method( )
crit = Critter(name = "Poochie", mood = "happy")
crit.talk( )crit.public_method( )
input("Press enter to leave")我收到以下错误：
Traceback (most recent call last):
File "/Users/calebmatthias/Document/workspace/de.vogella.python.first/practice.py", line 27, in <module>
crit = Critter(name = "Poochie", mood = "happy")
TypeError: object.__new__() takes no parameters回答 2

我建议您更仔细地格式化您的提交。Python在缩进方面非常挑剔--请阅读PEP8以获得有关如何正确格式化Python代码的良好介绍。
问题是你把__init__拼错了。你有_init_，它只是Python的另一种方法。

请注意，以下更正的代码运行正常(_init_更改为__init__；_mood更改为__mood；public_method更改为public；缩进已更正)：
class Critter(object):
"""A virtual pet"""
def __init__(self, name, mood):
print("A new critter has been born!!!!!")
self.name = name
self.__mood = mood
def talk(self):
print("\n Im",self.name)
print("Right now I feel",self.__mood)
def _private_method(self):
print("this is a private method")
def public(self):
print("This is a public method. ")
self._private_method( )
crit = Critter(name="Poochie", mood="happy")
crit.talk()
crit.public()
input("Press enter to leave")对输出执行...and操作：
A new critter has been born!!!!!
Im Poochie
Right now I feel happy
This is a public method.
this is a private method
