Python 动态添加属性总是 returns 相同的结果

Question

我对 python 比较陌生。我创建了这个最小示例来演示我的问题。在一个循环中，我在运行时向 class 添加了一些属性。如果我稍后查询属性，我总是会得到相同的结果。我打印并检查了函数和属性的函数实例变量，它们都与预期的不同。当我调用属性时，我总是以最后一个属性.

的结果结束

class T:
    def __init__(self):
        specialList = ['MIN', 'DEF', 'MAX']
        for special in specialList:  
            def get_property_special(self):
                print('return get_current('+special+')') #call getter with special parameter
                return special # just fake here. Should return value of getter
            
            print("Dyn function", get_property_special)
            specialProp = property()
            print("Property "+ str(specialProp))
            specialProp = specialProp.getter(get_property_special)
            setattr(T, "current_" + special.lower(), specialProp)
            print ("define property: current_" + special.lower())
               
b = T()
print(b.current_max)
print(b.current_min)
print(b.current_def)

结果：

Dyn function <function T.__init__.<locals>.get_property_special at 0x0000026D6D8805E0>
Property <property object at 0x0000026D6D8929A0>
define property: current_min
Dyn function <function T.__init__.<locals>.get_property_special at 0x0000026D6D8A9790>
Property <property object at 0x0000026D6D892AE0>
define property: current_def
Dyn function <function T.__init__.<locals>.get_property_special at 0x0000026D6D8A94C0>
Property <property object at 0x0000026D6D892B30>
define property: current_max
get_current(MAX) #ok
MAX
get_current(MAX) #Error: why MAX called min
MAX
get_current(MAX) #Error: why MAX called def
MAX

编辑：我希望属性使用参数 MIN、MAX、DEF

调用 getter

根据 David Meu 的提示，我修改了代码，现在可以运行了：

class T:
def __init__(self):
    specialList = ['MIN', 'DEF', 'MAX']
    for special in specialList:  
        def get_property_special(self, sp = special):
            print('return get_current('+sp+')') #call getter with special parameter
            return sp   # just fake here. Should return value of getter
        
        print("Dyn function", get_property_special)
        specialProp = property()
        print("Property "+ str(specialProp))
        specialProp = specialProp.getter(get_property_special)
        setattr(T, "current_" + special.lower(), specialProp)
        print ("define property: current_" + special.lower())
           
b = T()
print(b.current_max)
print(b.current_min)
print(b.current_def)
