Don't try to get the database connection. It's impossible (well, not
really). Instead try to realise the truth: use an sql method.

Don't bother. Let sqlvar do the quoting work for you:
Add a ZMySQLDA Connector object to your site (let's call it 'conn').
Add a ZSQLMethod to your site (let's call it 'save') pointed at the
'conn' connector, with parameters:
insert into myDictTable (dictNameColumn, dictPickleColumn) values
(<dtml-sqlvar name type='string'>,
<dtml-sqlvar dict type='string'>)
and in your python script you just do
container.save("my dictionary name", myDict).
considerations about database schema and retrieval of the dictionary are
left as an exercise for the reader.
Ideas don't stay in some minds very long because they don't like
