Question

首先，在谈到代码时，我想说的是一个总的菜鸟。我在学校攻读CS学位，python是我的第一语言。我应该创建一个动物园类，根据我提供的参数打印出信息。由于某种原因，我无法得到这个编译，我甚至不确定我正在做什么。我的老师老师正在度假，所以副手真的很有帮助。谢谢你们

Answer 1

您使用__init__()定义快速放松，然后在调用时遗漏了一些内容。

如果您想以标准方式创建各种动物对象，则必须以标准方式定义它们。使用kid, animalType, legs, age, feature但kid, legs, age, animalType, feature将不允许您这样做（我建议使用标准self来引用对象的实例，而不是kid）。

当你尝试制作动物时，你会提供它的类型，腿数和年龄，但你从未告诉过构造函数feature是什么。其他的是在程序顶部附近定义的（我建议顺便从循环中取出类定义），但feature无处可寻。以某种方式定义它，或者完全忽略对feature的引用（即，使用kid1= Cub(kind, legs, age)之类的内容）以降至默认值。

为什么功能没有定义python
