I'm using gremlin-python to connect to gremlin-server and I'm trying to build up a query incrementally but I'm getting stuck. I have an initial part of my query like the following:
query = g.V().hasLabel('<some_label>')
Now I would like to do multiple things with this query, firstly I just want a count:
query.count().next()
Now if I do anything else using the query variable the count step is on the traversal, so something like the following doesn't work:
query.out('<some_edge_label>').valueMap().toList()
Looking at the docs it seems like I need to clone the traversal so I replaced the above with:
query = g.V().hasLabel('<some_label>')
count_query = query.clone()
count_query.count().next()
But query still has the count() step on it, when I print the bytecode even though I cloned it. Is this the expected behaviour for gremlin-python? Here is a complete example of what I'm talking about, printing the bytecode at each step:
query = g.V().hasLabel('alabel')
print(query)
q_count = query.clone()
print(q_count.count())
print(query)
[['V'], ['hasLabel', 'alabel']]
[['V'], ['hasLabel', 'alabel'], ['count']]
[['V'], ['hasLabel', 'alabel'], ['count']]
What do I do to clone/copy the start of the traversal so I can reuse it in gremlin-python?
