The config.db of each mailing list is a marshalled Python dictionary, which
contains members and digest_members dictionaries.  The keys of those two
dictionaries are the lower case mail addresses of subscribers.  MailList
provides functions GetMembers() and GetDigestMembers() for getting the
subscriber lists (or GetDeliveryMembers(), GetDigestDeliveryMembers() to
preserve case in the usernames).

list_members output file format is a simple list of subscribers' Email

You might also want to investigate bin/withlist which provides a
framework for examining and modifying a list database, with optional
locking of the database to permit safe modifications.  You can use
withlist to apply a function to a list using the -r switch.

$python -i bin/withlist my-list
>>> print m.GetMembers()
