TypeError:object()不带参数

Question

我的代码生成以下错误: TypeError: object() takes no parameters

class Graph(object):
    def vertices(self):
        return list(self.__graph_dict.keys())

if __name__ == "__main__":

    g = { "a" : ["d"],
          "b" : ["c"],
          "c" : ["b", "c", "d", "e"],
          "d" : ["a", "c"],
          "e" : ["c"],
          "f" : []
        }

    graph = Graph(g)

    print("Vertices of graph:")
    print(graph.vertices())

有没有办法解决这个问题？

__init__因此,当您调用时,Graph类不带任何参数:

graph =图(g)

您收到错误,因为Graph不知道如何处理'g'.我想你可能想要的是:

class Graph(object):    
    def __init__(self, values):
        self.__graph_dict = values
    def vertices(self):
        return list(self.__graph_dict.keys())
