Hi, I'm starting to use hamilton and have been loving it so far. I tried making a function that returns a tuple:

def get_range() -> (int, int): return (1, 3)

And when I ran my pipeline it duplicated the data into 2 rows:

other_column get_range
Some Text    1
Some Text    3

But I wanted just one row:

other_column get_range
Some Text    (1, 3)

Is there any way to do that, or am I designing my pipeline wrong?

@Alan Morgan how are you constructing the driver?

Just very basic:

dr = driver.Driver({}, demo)
df = dr.execute(dr.list_available_variables(), inputs={})
print(df)

I'd rather a dictionary be the output.

yep — that explains the behavior. Try:

dr = (
 driver.Builder()
   .with_config({})
   .with_modules(demo)
   .build()
)

Ah, okay, I see the doc saying builder defaults to dict type.

This defaults to making the driver return a dictionary when

.execute()

is called.

thanks.
