Smart way to convert a PoolMemberDefinitionSequenceSequence to a IPPortDefinitionSequenceSequence

i don't really understand the shortcuts you've taken with the for loops here:

 

pmemseq.item = [x.members for x in [y for y in data_list]]

 

member_status = poolmemobj.get_enabled_state(pool_names = [x.pool for x in data_list], members = [pmemseq])

 

 

what would each of these look like expanded? whats a good python reference keyword i can search on to see these explained?

 

 

it looks like the reverse of nested for loops, which is what i was working on except i couldn't figure out how to create a sequence of IPPortDefinition i could then assign via the '.item' method(?)

 

 

so for example, would [x.members for x in [y for y in data_list]] expand similar to:

 

for y in data_list:

 

for x in y
