j= lambda l:reduce(lambda a,b:a+b,l)
k= lambda l:map(lambda z:j(z),map(lambda x:k(x) if type(x)==list else [x],l))
Type Error: it prints [1, 14] for print k([1,[2,[3,4],5]])

Sometimes, one liners are a pain to the eyes – Sheldore Oct 16 '18 at 11:35

So I am just curious on your approach to this, did you try to write this out as a mulit line function before converting to a one liner? That way you can verify your code was working before optimizing it into a one liner – B. Cratty Oct 16 '18 at 11:36

Maybe [here](https://stackoverflow.com/questions/952914/making-a-flat-list-out-of-list-of-lists-in-python) you can find something – Novak Oct 16 '18 at 11:38

yes with a multi line function it's much easier – MichaelCracker Oct 16 '18 at 11:38

@Novak the solution is only for 2 in depth, i need it to be for infinite depth – MichaelCracker Oct 16 '18 at 11:41

1Can you possibly add the mulit line function to the post so I can see what you are converting from? – B. Cratty Oct 16 '18 at 11:42

You can try the solution proposed in:
flatten=lambda l: sum(map(flatten,l),[]) if isinstance(l,list) else [l]
