Python实例没有__call__方法

Question

在放弃丑陋的bash脚本之后,我一直在学习如何在今天的大部分时间里使用Python.

我正在尝试使用2个类来定义一些对象数组,其中存储一些唯一的字符串和整数(1-10).对象将包括以下内容:

object[i].user
         .n     # n = i
         .name
         .coords
         .hero

(param1,param2,param3)对于每个object.n和object.user都是不同的,所以我在尝试使用一个在编写90个唯一字符串后看起来不像垃圾的赋值方法.嵌套我发现的例子不起作用,所以这里是妥协:

class CityBean:
    def __init__(self,name,coords,hero):
        self.name = name
        self.coords = coords
        self.hero = hero

class Castles:
    def __init__(self,user,n):
        self.user = user
        self.n = n
        if self.user == 'user1':
            temp = {
                1:  CityBean( "name1"  , "coord1" , "hero1"),
                ... blah blah blah
                10: CityBean( "name10" , "coord10" , "hero10" )}[self.n]()
        if self.user == 'user2':
            temp = {
                1:  CityBean( "name11" , "coord11" , "hero11" ),
                ... blah blah blah
                10: CityBean( "name20" , "coord20" , "hero20" ) }[self.n]()
        if self.user == 'user3':
            temp = {
                1:  CityBean( "name21" , "coord21" , "hero21" ),
                ... blah blah blah
                10: CityBean( "name30" , "coord30" , "hero30" ) }[self.n]()
        self.name = temp.name
        self.coords = temp.coords
        self.hero = temp.coords
        __del__(temp)

我称之为:

cities = list( Castles("user2",i) for i in range(1,11) )

它给了我这个错误:

AttributeError: CityBean instance has no __call__ method

它归咎于这一行:

                10: CityBean( "name20" , "coord20" , "hero20" ) }[self.n]() # pseudo
                10: CityBean( "" , "" , "" ) }[self.n]() # what is actually looks like

我的邋classes班有什么问题？我做了一些迟钝的事,不是吗？

很难从你提供的内容中猜出你想要什么,因为你提供了新手代码,而不是说你想做什么,所以你的猜测时间很长.

我认为这样的事情会做:

data = {
        (1, 'user1'): ("name1", "coord1", "hero1"),
        (2, 'user1'): ("name2", "coord2", "hero2"),
        #...
        (1, 'user2'): ("name11", "coord11", "hero11"),
        (2, 'user2'): ("name12", "coord12", "hero12"),
        # ...
    }


class CityBean:
    def __init__(self,name,coords,hero):
        self.name = name
        self.coords = coords
        self.hero = hero

class Castles:
    def __init__(self,user,n):
        self.user = user
        self.n = n
        name, coords, hero = data.get((n, user))
        self.citybean = CityBean(name, coords, hero)
