I’m trying to have nested looping but I also want one of the lists to only be run through once. e.g. if i had 3 lists x=[‘a’, ‘b’] y=[‘1’] z=[‘A’, ‘B’] I would do something like:
with_together:
- [‘a’, ‘b’]
- with_nested:
- [‘1’]
- ['A,‘B’]
and what should come out is:
[‘a’,‘1’,‘A’]
[‘b’,‘1’,‘B’]
I tried a few variations of the above but it doesn’t seem to work that way. Is there a way to currently do this?
In python it would be something similar to:
import itertools
x=[‘a’,‘b’]
y=[‘1’]
z=[‘A’,‘B’]
a=list(itertools.product(y,z))
b=[i for i in a]
c=zip(x,b)
d=
for sublist in c:
d.append(list(itertools.chain.from_iterable(sublist)))
The practical end goal of this is I am creating a bunch of new EBS volumes based off of snapshots in EC2 (using the ec2_vol module) and want to attach them to an instance without reusing the same snapshot twice and being able to list the device names they should be bound to e.g.
[/dev/sdf, /dev/sdg]
[aws-id-123]
[snapshot-id-0001, snapshot-id-0002]
gets transformed to:
[/dev/sdf, aws-id-123, snapshot-id-0001]
[/dev/sdg, aws-id-123, snapshot-id-0002]
