Tie dictionary to database table?

[Peter Heitzer]

In Perl there exists the tie mechanism for key/value type databases like
Berkeley db. Are there any python modules that can do the same for
a column of a mysql table?
Given the following table users:
(
username char(16) not null unique,
email char(128),
fullname char(64)
)

What I would like is if I write 

email['frank']='frank at middle-of-nowhere.org'

in my python script it generates a statement like
update users set email='frank at middle-of-nowhere.org' where username='frank';

Any hints to already existing modules are highly appreciated.



and have
