Question

在玩文字游戏时，我遇到了一个错误，其中playercharacter没有分配我给它的任何变量。运行示例如下：

What is your name?
Ty

playercharacter.getname()

Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
playercharacter.getname()

AttributeError: 'player' object has no attribute 'getname'

无论我尝试调用哪个属性，它都会返回相同的错误消息。

我在这里做什么错了？

这是下面的完整代码：

    def __init__(self, name, level, ST, PE, EN, CH, IN, AG, LK, location, HP, XP, NXTLVL):

此外，任何一般性建议都很好，谢谢！

Answer 1

您过度缩进了其他方法；所有def get*名称的缩进级别应与def __init__相同，而不是__init__的内容级别。

就一般建议而言：不要编写Java风格的访问器。 Python的方法是直接访问属性，或者如果您坚持某种保护，则使用前导下划线命名实例属性，并使用@property访问器。因此，如果name应该受到保护以免发生突变，那么您将：

def __init__(self, ...):
    self._name = ...

@property
def name(self):
    return self._name

因此该属性的使用仍然为myobj.name，而无需显式调用函数或使用多余的get前缀。

属性没有分配给班级？ Python 2.7
