The Python Database API (DB-API) defines a standard interface for Python database access modules. It’s documented in PEP 249. Nearly all Python database modules such as sqlite3, psycopg and mysql-python conform to this interface.
Tutorials that explain how to work with modules that conform to this interface can be found here and here.
