Hi,
I am having an issue with passing values from one function to another
- I am trying to fill a list in one function using the values
contained in other functions as seen below:
infinity = 1000000
invalid_node = -1
startNode = 0
#Values to assign to each node
class Node:
distFromSource = infinity
previous = invalid_node
visited = False
#read in all network nodes
def network():
f = open ('network.txt', 'r')
theNetwork = [[int(node) for node in line.split(',')] for line in
f.readlines()]
print theNetwork
return theNetwork
#for each node assign default values
def populateNodeTable():
nodeTable = []
index = 0
f = open('network.txt', 'r')
for line in f:
node = map(int, line.split(','))
nodeTable.append(Node())
print "The previous node is " ,nodeTable[index].previous
print "The distance from source is
" ,nodeTable[index].distFromSource
index +=1
nodeTable[startNode].distFromSource = 0
return nodeTable
#find the nearest neighbour to a particular node
def nearestNeighbour(currentNode, theNetwork):
nearestNeighbour = []
nodeIndex = 0
for node in nodeTable:
if node != 0 and currentNode.visited == false:
nearestNeighbour.append(nodeIndex)
nodeIndex +=1
return nearestNeighbour
if __name__ == "__main__":
nodeTable = populateNodeTable()
theNetwork = network()
nearestNeighbour(currentNode, theNetwork, )
So, I am trying to look at the values provided by the network
function, set all nodes to 'visited = false' in populateNodeTable
function and then determine the nodes' nearest neighbour by looking at
the values provided in the previous function, though I get this error
message:
if node != 0 and currentNode.visited == false:
AttributeError: 'int' object has no attribute 'visited'
I'm not sure what to try next
