Currently these functions fail if the supplied object has no len(). There are algorithms for this task that can work on any finite iterator (for example, files as a stream of lines), and the functions could fall back to these if there is no len().
I like the idea, as long as it does not add too much overhead to currently existing code.
It could be a special code path for reservoir sampling (I assume) for both functions (the first taking only one sample from the stream).
