python中self的动态引用属性

我目前在python（django）函数中有一系列语言检查：

def __get__(self, instance, owner):

  if translation.get_language() == 'fr':
    trans_field = getattr(instance, self.fr_field)
  else:
    return getattr(instance, self.en_field)

我要做的是在循环中运行：

for language in languages:
  if translation.get_language() == language:
    return getattr(instance, self.[language]_field)
  else:
    return getattr(instance, self.en_field)

---

我该怎么做？显然，

self.[language]\u字段

是伪代码

您已经有了解决方案。使用getattr

---

getattr（实例，getattr（self，language+''u field'））

您已经有了解决方案。使用getattr

---

getattr（实例，getattr（self，language+''u field'））

第二次使用

getattr

：

return getattr(instance, gettattr(self, '{}_field'.format(language))

---

再次使用

getattr

：

return getattr(instance, gettattr(self, '{}_field'.format(language))

---

谢谢是否有一种方法也可以在init函数中分配此变量，即

def uuu init_uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu？现在我也在静态地声明它们：
self.en_field=en_field
，
self.fr_field=fr_field
您可以使用
setattr
