I have a list that looks like this:

lst = [4, 6, 7, 8, 12, 15, 16, 17, 18, 19, 9, 28, 29]

I'd like to generate a nested list where the original list is broken into sublist of consecutive numbers:

sub_list = [[4], [6, 7, 8, 9], [12], [15, 16, 17, 18, 19], [28, 29]

I'm struggling to figure out how I can do this. Can anyone provide a function to generate this?

Turns out it's like a duplicate :) – alecxe Aug 28 '13 at 20:17
Most excellent! Thanks. Should have known, groupby is frequently the answer for this type of thing. – turtle Aug 28 '13 at 20:22
This is *not* a duplicate because the original list isn't sorted. The accepted answers to the other questions aren't applicable here. – flornquake Aug 28 '13 at 21:03
