I agree, completely!

Ok, I think I'm going to provide both the simplified interface and the
class to instantiate. Thanks all!

Now suppose, this class looks like:

class StateMachine(object):
    def __init__...
    def function0...
    def function1...
    def function2...
    ...

up to many. And later in the library I would like to expose the
simplified interface as well:

_machine = StateMachine()
function0 = _machine.function0
function1 = _machine.function1
function2 = _machine.function2
...

Is there a way to do so in a programmatic way? Like:

_machine = StateMachine()
for function in {every function in _machine}:
    function = _machine.function

Not that it's difficult to copy-paste some lines, I'm just curious and
maybe it would be a tiny bit easier to maintain the library.
