That's about it. If you think about C++ public members as the
"interface" and private/protected members as the "implementation",
then Python's convention is a leading underscore on the latter; you
can reasonably expect that non-underscore members can be trusted to be
maintained, but underscored members will quite possibly change in
subsequent versions.

Among smart people, conventions like this are all you need.
