Others have already mentioned that python's re has a split function,
but for a single character, I suspect the string method might be
faster. And since the it is not a variable pattern, you know what's
going to be returned, so why bother getting the ':' back?

You can always reconstitute the original with ':'join(pieces), e.g.

 >>> s = 'test:one:two:three'
 >>> sl = s.split(':')
 >>> sl
 ['test', 'one', 'two', 'three']
 >>> ':'.join(sl)
 'test:one:two:three'

Or mess with the pieces and join them differently

 >>> map(str.title, sl)
 ['Test', 'One', 'Two', 'Three']
 >>> ' :: '.join(map(str.title, sl))
 'Test :: One :: Two :: Three'

Just curious, what did you need the ':'s for?
