Here's a solution that works for iterables other than lists:
py> def collapse(iterable): ... enumeration = enumerate(iterable) ... _, lastitem = enumeration.next() ... yield lastitem ... for i, item in enumeration: ... if item != lastitem: ... yield item ... lastitem = item ... py> lst = [0,0,1,1,1,2,2,3,3,3,2,2,2,4,4,4,5] py> list(collapse(lst)) [0, 1, 2, 3, 2, 4, 5]
Again, I'm still not sure I'd call this more elegant...
Hmmmm, what role does the enumeration play here?
None =) Sorry, it was an accidental carry-over from the list solution that looked at lst[i-1]. I thought about correcting it when I realized this (after posting), but I was too lazy. ;)
