Super! Thank you very much. Here is the working final (I hope the

How to change the Deliverymode for users in one
list from MIME Digest to PlainText Digest
su mailman
(venv)$ mailman shell -l mylist@mydomain.com
Welcome to the GNU Mailman shell
Use commit() to commit changes.
Use abort() to discard changes since the last commit.
Exit with ctrl+D does an implicit commit() but exit() does not.
The variable 'm' is the mylist@mydomain.com mailing list

...
from mailman.interfaces.member import DeliveryMode
for member in m.subscribers.members:
...        if member.delivery_mode != DeliveryMode.regular:
...            member.preferences.delivery_mode =
DeliveryMode.plaintext_digests
...
commit()
exit()

NOTE TO SELF:
Line 10 use 1 tab or 4 spaces after the first ellipse
Line 11 use 2 tabs or 8 spaces after the second ellipse.
Line 12 <ENTER>after the third and final ellipse
