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:
    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 )


srva@hades:~$ python RW3.py --output topology.xml --xml germany50.xml
Traceback (most recent call last):
   File "RW3.py", line 157, in <module>
   File "RW3.py", line 152, in main
   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. Thank You

You've set your editor to display tabs as 4 spaces, but then you've sometimes used tabs in your file, and sometimes 4 spaces. Look at how your code is indented in your post: the addNode and addEdge definitions are indented with tab characters instead of spaces, so Python thinks they are eight spaces in. This makes them defined inside of __init__, rather than as part of your class.

Set your editor to insert spaces when you use the Tab key, and set it to use 4-space indents. Then find all the tab characters in your file and replace them with the proper number of spaces.
