Allow row selection using subscript notation #31

Open s-leroux opened 3 months ago

s-leroux commented 3 months ago

Currently, subscript notation in Serie only allows the selection of columns:

We may extend the supported notation to allow row selection as well. At a minimum, we may allow row selection based on index and index range. ~Possibly required by #30.~

We may use one of two "special" Python notations here. Either ... (the ellipsis) or : (the empty slice).

series["DATE","CLOSE",:,1:5]

vs

series["DATE","CLOSE",...,1:5]
