My understanding is that in python this is not possible. Can you
confirm?
Your understanding is correct.
The Python convention is to prefix non-public methods/classes etc with
an underscore, as in _doSomethingDangerous(). This is meant to
indicate to anyone using your module that they shouldn't use this
function, at least not without having a good understanding of what it
does.

You could add a little bit of protection by always passing a certain
object into _doSomethingDangerous().
_guard = object()
def _doSomethingDangerous(g):
if g is not _guard:
raise Exception("Don't do that!")
That would at least stop accidental calls.
