获取“未解析的引用”错误

Question

我一直收到一个“未解决的引用”错误，尽管我对它做了一个声明。

verb_dict = {"say": say, "examine": examine}

错误发生在examine之后

def examine(noun):
    if noun in GameObject.objects:
        return GameObject.objects[noun].get_desc()
    else:
        return "There is no {}".format(noun)

我在编码的时候做错了什么吗？

我也在使用pycharm社区版。

Answer 1

我无法在PyCharm 2016.14中复制您的问题我运行以下代码时没有任何问题：

class GameObject:
    class_name = ""
    objects = {}

    def __init__(self, name):
        self.name = name
        GameObject.objects[self.class_name] = self


def examine(noun):
    if noun in GameObject.objects:
        return GameObject.objects[noun].get_desc()
    else:
        return "There is no {}".format(noun)

print(examine('try'))

输出为

>>> There is no try

Answer 2

这是GameObject类。我看不出there.If有什么问题，你需要更多的告诉我。

class GameObject:
    class_name = ""
    desc = ""
    objects = {}
    def __init__(self, name):

        self.name = name
        GameObject.objects[self.class_name] = self
