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 )
...
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. 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.
