get: [ 0, 1, 3, 4, 5, 5, 5, 7, 10 ]
  What is the best way (or pythonic way) to get this.

Homework?

not really :)

It's just that I was wondering if a built-in function for doing such
things (which I find myself doing increasingly with an explicit loop)
exists.

Why would you find yourself doing it more than once? Write it once in a
function and then just re-use the code.
