If you want to follow the web.py tutorial using sqlite here’s how:

Line for your python to connect to DB

db = web.database(dbn='sqlite', db='testdb')

To create the database type

sqlite3 testdb

and input this SQL:

CREATE TABLE todo (id integer primary key, title text, created date, done boolean default 'f');
CREATE TRIGGER insert_todo_created after insert on todo
begin
update todo set created = datetime('now')
where rowid = new.rowid;
end;

Now create an entry with this SQL

insert into todo (title) values ('Learn web.py');

Finally quit sqlite3 when your ready by typing

.quit
