Smart way to convert a PoolMemberDefinitionSequenceSequence to a IPPortDefinitionSequenceSequence

Have a look at 'list comprehensions'. They're extremely handy in situations like this. Think of them as an easy way to create a list from another iterable after you've manipulated it in some way. Similar to map(). So expanded, this:

 

[x.pool for x in data_list] translates to something like:

 

 

for x in data_list:

 

x.pool

 

 

but it returns a list of the returned items, not the items individually. That second comprehension is nested, and they'll bend your mind if you're coming into them new. I usually avoid nested comprehensions but for some reason it felt natural to do it in your case.

 

So you're dead right:the purpose of: [x.members for x in [y for y in data_list]] is to essentially get a the members attribute of the returned objects from get_member(). I needed a way to flatten out that list to nothing more than the pool members as defined by their IPPortDefinitions.
