Hello Friends, I am working on this code but I kind of get the same error over and over again. Could any of you help me fix this part of the error?
File RW1: class PHY_NETWORK: def __init__(self, nodes, edges): self.nodes = nodes self.edges = edges def addNode(self, node): self.nodes.append( node ) def addEdge(self, edge): self.edges.append( edge ) File RW3: def createnetwork(graph): doc = parse( args.paramFile ) noderef = [] num = 0 nodelist = doc.getElementsByTagName("node") for node in nodelist: noderef.append(node.getAttribute("id")) proc = random.randint(3500, 5000) stor = random.randint(7200, 8200) switch = random.randint(7000, 10000) num = num + 1 totaldemands = random.randint(1, 5) graph.addNode(PHY_NODES( node.getAttribute("id"), int(num), float(xCoordinates.firstChild.data), float(yCoordinates.firstChild.data), float(proc), float(stor), float(switch), int(totaldemands))) linkid = 0 linklist = doc.getElementsByTagName("link") for link in linklist : linkid = linkid + 1 Source = link.getElementsByTagName("source") [0] Destination = link.getElementsByTagName("target") [0] Capacity = link.getElementsByTagName("capacity") [0] SourceID = noderef.index(Source.firstChild.data) + 1 DestinationID = noderef.index(Destination.firstChild.data) + 1 graph.addEdge( PHY_LINKS( linkid, Source.firstChild.data, Destination.firstChild.data, DestinationID, SourceID, float(Capacity.firstChild.data) )) global args args = parser.parse_args() samplenetwork = PHY_NETWORK([], []) for i in range(1, 100): createnetwork(samplenetwork) exportXmlFile(samplenetwork, args.output, 'a' ) if __name__ == "__main__": main(sys.argv[1:]) srva@hades:~$ python RW3.py --output topology.xml --xml germany50.xml Traceback (most recent call last): File "RW3.py", line 157, in <module> main(sys.argv[1:]) File "RW3.py", line 152, in main createnetwork(samplenetwork) File "RW3.py", line 31, in createnetwork graph.addNode(PHY_NODES( node.getAttribute("id"), int(num), float(xCoordinates.firstChild.data), float(yCoordinates.firstChild.data), float(proc), float(stor), float(switch), int(totaldemands))) AttributeError: PHY_NETWORK instance has no attribute 'addNode' The error that it give back is as above. I have the classes defined in RW1 file and I am importing the classes onto RW3 file and yet, It doesn't seem to work. I really am in need of your valuable suggestions.
