Yes! There are a few. Quick q — is this a single function (query), or a bunch of functions?

Currently it is one function/database query

OK, so it should be pretty easy:

@parameterize(
    query_1={'query_param' : source('query_param_source_1'),
    query_2={'query_param' : source('query_param_source_2')
)
def query(query_param: ...) -> ...::
    return do_something_with(query_param)

This would be equivalent to defining the same one twice with the same logic but different params. E.G.

def query_1(query_param_source_1: ...) -> ...:
    return do_something_with(query_param)

def query_2(query_param_source_2: ...) -> ...:
    return do_something_with(query_param)

I see, that's intuitive if you know pytest

@Elijah Ben Izzy I think you have typos - the arguments/sources need to be different between them.

@Stefan Krawczyk yep you’re correct, fixed it. And @David Wesolowski yeah! Turns out Hamilton + pytest have some very similar approaches (this is very much like the parametrized decorator). Funny that I didn’t actually learn pytest.mark.parametrized until after we built Hamilton…

except that you spell it correctly 🙂

lmao @Stefan Krawczyk and I had quite a back and forth about the spelling 😆 We used to spell it wrong then we deprecated them
