TypeError：尝试调用方法时“元组”对象不可调用

Question

这是我到目前为止所做的：

# -*- coding: cp1252 -*-
import time

class Item():
    def __init__(self, name, description, base_value):
        self.name = name
        self.description = description
        self.ingredients = ingredients
        self.base_value = value
    def __str__(self):
        return format(self.name, self.description, self.ingredients, self.base_value)


class Metal(Item):
    def __init__(self, name, description, ingredients, base_value):
        self.smelt_time = smelt_time
        self.smelted = smelted
    def __str__(self):
        return format(self.name, self.description, self.ingredients, self.base_value, self.smelt_time, self.smelted)

class Bronze_Ingot(Metal):
    def __init__(self):
        self.name = "Bronze Ingot",
        self.description = "A refined ingot of bronze."
        #self.ingredients = Tin_Ore(1)+Copper_Ore(1) <--- I will get these lines working later...
        self.base_value = 33
        self.smelt_time = 15
        self.smelted = ()            

class Fuel(Item):
    def __init__(self, name, description, ingredients, base_value):
        self.fuel_time = fuel_time
    def __str__(self):
        return format(self.name, self.description, self.ingredients, self.base_value, self.fuel_time)

class Cloth(Fuel):
    def __init__(self):
        self.name = "Cloth",
        self.description = "A piece of cotton cloth."
        #self.ingredients = 2 Cotton <--- I will get these lines working later... 
        self.base_value = 2
        self.fuel_time = 5

但是我在使用这个功能时遇到了很大的麻烦......

    def smelted(Fuel, Metal):
        if (Fuel.fuel_time - Metal.smelt_time) > 0:
            time.sleep(1)
            print "Smelting", Metal.name, "..."
            time.sleep(Metal.smelt_time)
            print "Time to forge!"

问题或多或少是让它发挥作用。我和我的朋友已经尝试了 我们 在运行此功能时可以想到的所有方法，但无济于事。这是我们最近的尝试：

from Smelting_Progress import *

x = Cloth()
y = Bronze_Ingot()

y.smelted(x,y)

尝试运行后，我收到此错误：

Traceback (most recent call last):
File "C:\Users\WCS-HSSTUDENT\Desktop\Files\Project SAOffline\Coding\New Aincrad World\Items\NAI_Smelted.pyw", line 6, in <module>
    Metal.smelted(Fuel, Metal)
TypeError: 'tuple' object is not callable

Answer 1

你有一个实例属性smelted；你把它设置在Metal.__init__():

self.smelted = smelted

您的 Bronze_Ingot 子类将其设置为一个空元组：

self.smelted = ()            

您不能同时让方法和元组使用相同的名称。重命名一个或另一个。

如果您打算将smelted() 代码用作函数，则在顶层定义它（与您的类相同的缩进），并将其作为函数而不是方法调用：

smelted(x, y)

（注意，前面没有y.）。
