There are two thing named sqlite3 at play here:
First, the sqlite3 module that is part of the standard library for Python 2.5
and newer. The fact that's it's included means, in your platform, some files
and directories named sqlite3.* and _sqlite3 under your C:\python2x
installation directory, but you aren't supposed to mess with them because they
are an implementation detail and you'd be breaking your Python installation if
you did (just for completeness: they are the SQLite library in a dynamic
library form and the Python DB-API 2module that allows Python programs like
Django to access SQLite databases).
Second there is the sqlite3.exe utility that can be download from SQLIte web
site. It's a program that also knows how to access SQLite databases because it
includes the SQLite library compiled statically for its own use (so the program
can be used in an standalone fashion).
The dbshell Django management command uses this utility. So you need
to download sqlite3.exe if you want to use it.
