[Zope] How do I connect to a db from a PythonMethod?

I have this in an ExternalMethod and it works fine: import MySQLdb conn = MySQLdb.Connection(user='xxxx', passwd='yyyyy', db='zzz') In a PythonMethod, it fails because of the import restriction. What's the easiest way to get around this. I'm not getting anything out of the documentation in PythonMethods/ModuleSecurityInfo because it never says where the code snippets should actually go.
