我有以下python代碼：import networkx as nx def cost(i, j, d, value1, value2):    # some operation involving all these values    return cost# graph is a networkx graph# src, dst are integers# cost is a callable that is passed 3 values automatically i.e. src, dst and d # d is a dictionary of edge weightspath = nx.dijkstra_path(graph, src, dst, weight=cost)現在我想通過兩個值value1，并value2給cost功能。該networkx文件表示，weight可以接受恰好3參數的調用。但我需要value1和value2進行計算。如何才能做到這一點？編輯 使用 functools 的解決方案效果很好。但是，我的函數在一個類中，如下所示：import networkx as nx import functoolsclass Myclass:    def cost(self, i, j, d, value2):        # some operation involving all these values        # also need self    # graph is a networkx graph    # src, dst are integers    # cost is a callable that is passed 3 values automatically i.e. src, dst and d     # d is a dictionary of edge weights    # path = nx.dijkstra_path(graph, src, dst, cost)    cost_partial = functools.partial(cost, self=self, value2=5)    path = nx.dijkstra_path(graph, src, dst, cost_partial)使用這種方法，nx.dijkstra_path堅持分配src給self. 因此解釋器抱怨self分配了多個值。我需要 self 來計算成本。
