It's not really a matter of the collection, but more a matter of
serialization format/library.

If you want the serialized representation to be human-readable, use
JSON (http://docs.python.org/library/json.html#module-json).
If that's not a requirement, use pickle
(http://docs.python.org/library/pickle.html#module-pickle).
Both modules can convert simple Python data, such as your list of
floats, to a bytestream and back again.

Cheers,
Chris
