Python：TypeError：__init __（）恰好接受2个参数（给定1个） [英] Python: TypeError: __init__() takes exactly 2 arguments (1 given)

问题描述

我知道这个问题已经问过几次了，但是没有一个人能为我提供解决问题的方法。我读了这些：

I know this question has been asked several times, but none have managed to provide me with a solution to my issue. I read these:

__ init __（）正好接受2个参数（给定1个）？

类__init __（）恰好接受2个参数（给定1个）

试图做的是为生存游戏创建两个类，就像一个非常糟糕的《我的世界》版本。贝娄是两个类的完整代码：

All I am trying to do is create two classes for a "survival game" much like a very crappy version of minecraft. Bellow is the full code for the two classes:

class Player:
    '''
    Actions directly relating to the player/character.
    '''
    def __init__(self, name):
        self.name = name
        self.health = 10
        self.shelter = False

    def eat(self, food):
        self.food = Food
        if (food == 'apple'):
            Food().apple()

        elif (food == 'pork'):
            Food().pork()

        elif (food == 'beef'):
            Food().beef()

        elif (food == 'stew'):
            Food().stew()

class Food:
    '''
    Available foods and their properties.
    '''
    player = Player()

    def __init__(self):
        useless = 1
        Amount.apple = 0
        Amount.pork = 0
        Amount.beef = 0
        Amount.stew = 0

    class Amount:   
        def apple(self):
            player.health += 10

        def pork(self):
            player.health += 20

        def beef(self):
            player.health += 30

        def stew(self):
            player.health += 25      

现在出现完整错误：

Traceback (most recent call last):
  File    "/home/promitheas/Desktop/programming/python/pygame/Survive/survive_classe  s.py", line 26, in <module>
    class Food:
  File     "/home/promitheas/Desktop/programming/python/pygame/Survive/survive_classe    s.py", line 30, in Food
    player = Player()
TypeError: __init__() takes exactly 2 arguments (1 given)

我只想使上课。

推荐答案

您使用的代码如下：

player = Player()

自 __ init __ 必须根据您的代码由一个名为 name 的参数提供。因此，要解决您的问题，只需为Player构造函数提供一个名称，就可以设置好：

This is an issue since the __init__ must be supplied by one parameter called name according to your code. Therefore, to solve your issue, just supply a name to the Player constructor and you are all set:

player = Player('sdfasf')
