How do I extend a python module to include extra functionality? (sqlite3)

Question

How would I extend the sqlite3 module so if I import Database I can do Database.connect() as an alias to sqlite3.connect(), but define extra non standard methods?

Why do you need that? Python is dynamic, so you can add extra functions and methods and whatnot to modules, but that does not mean that that is a good idea. Create your own module for that code instead. — Martijn Pieters

End users are sometimes not the brightest of people, so having a module which is an alias to the built in stuff but also with all the extra functionality I require would be an ideal situation. — illumi

You can create a class which wraps sqlite3. It takes its .connect() method and maybe others and exposes it to the outside, and then you add your own stuff.

Another option would be subclassing - if that works.

You could write your own Database module that has the following line at the top:

from sqlite import *

Then define methods as you like, but make sure you don't overwrite anything.
