If you make the whitespace more standard, use the tempfile module (to remove the os.remove line) and use with statements, the file is actually very short (so my earlier hypothesis about createdb was wrong :).

I think we could inline it (with a literalinclude directive) or link to it (with :source:`Doc/include/sqlite3/createdb.py`).  Add something like “If you want to run these examples, run this code to create and populate the initial database” and we’re set.
