It's the same back to at least Python 2.5, so you can probably rely on
that behaviour.

Interestingly, the documentation says:

"""This is equivalent to choice(range(start, stop, step)), but doesn’t 
actually build a range object."""

but for choice(seq) it says:

"""If seq is empty, raises IndexError."""

so it's not entirely equivalent.
