DNS, DB server based on Python?

[Brian Lee]

I'm looking for DNS and DB server based on Python language.
I use bind version 9 and mysql 3.24 on Linux but want to change
other server which is coded by Python language.

Performance and function of the servers is not important for me.
I want to try to read server code in Python.

Any comments will be helpful for me. Thank you.

ps. I don't care the database is rdbms or not.
