I am losing my mind with py2neo: node in the graph but not in the graph - py2neo

Question

So this is a graph that contains network devices
Preexisting nodes were added and now I am trying to add more nodes and add relationships to the graph. What am I doing wrong. At the bottom of the second block of code the error message is saying the node is not in this graph but as you can see the node is listed as present
matcher=NodeMatcher(db)
nodes=matcher.match()
for node in nodes:
print (node)
node1=matcher.match(name="mxxx103")
print (node1)
node2=matcher.match(name='mxxxcvss01')
print(node2)
for rel in db.relationships.match((node1,node2)):
print (rel)
And the output when running the above code
(_9787:Device {model: 'ASR1000', name: 'mxxx103', scanned: 'Yes'})
(_9788:Device {model: 'ASR1000', name: 'lxxx100', scanned: 'Yes'})

Answer 1

OK I managed to find the mistake, it seems that I need to look again and again over the return of each method and the data types py2neo uses
The below code worked. My mistake was to believe that the node.match returns a node. That is not the case. The below code worked
matcher=NodeMatcher(db)
nodes=matcher.match()
for node in nodes:
print (node)
node1=matcher.match(name="mdc103")
list (node1)
node2=matcher.match(name='mdccvss01')
list(node2)
type(node1)
node1 = db.evaluate('MATCH (x) WHERE x.name="mxxx103" RETURN(x)')
print(node1)
node2 = db.evaluate('MATCH (x) WHERE x.name="mxxxcvss01" RETURN(x)')
print(node2)
for rel in db.relationships.match((node1,node2)):
print (rel)
