Are you scripting the web interface and doing mass adds and removals or
are you directly calling the Python methods?

If the former, any mass subscribed users will get digests or not
depending on the value of the list attribute digest_is_default at the

If the latter, look at Mailman/OldStyleMemberships.py. In particular,
the methods getRegularMemberKeys() and getDigestMemberKeys() for
getting non-digest and digest member lists, and the addNewMember()
method which takes arguments of the form 'digest=yes|no'. Also see the
setMemberOption() method.
