I.e. if I have a class with two methods, doSomethingSafe() and

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.
There is, however, also the possibility of prefixing the method name
with '__'. The invokes 'name mangling', which makes it more difficult
(though not impossible, the idea is to avoid accidents) for the method
to be called from outside the class.
