Re: Use of locals() with SQL placeholders

On the sync benefit: you can keep it without handing the whole frame to execute(). Wrap the values in a namespace and pass vars():

    from types import SimpleNamespace

    params = SimpleNamespace(
        service_type=service_type,
        login_id=login_id,
        horizon=horizon,
    )
    csr.execute(sql, vars(params))

The binding set is closed and greppable, names stay in sync with the placeholders by construction, and unlike locals() it means the same thing at module scope and inside a function (at module scope, locals() is globals()).

I'm with Chris on the explicit-dict default, for what it's worth: the call site should tell you what the query consumes. The namespace just removes the repetition tax.
