[Numpy-discussion] BOF notes: Fernando's proposal: NumPy ndarray with named axes
Fri Jul 9 18:05:39 CDT 2010
There has been a lot of great discussion about this -- and I"m really
glad to see it happening -- I've been putting off refactoring my own
lame, limited, poorly designed, special purpose version of this for ages.
One question I have (that may have been answered) is about slicing:
I think there has been mention of slicing dataarrays according to names
(would that be tick names?), but I'm not sure how that would work. There
are two orders:
The order that the data is in the array. i.e. the regular index order
The order you would get by sorting the ticks (assuming that the tick
names are sortable -- datetimes, numbers, strings, etc)
So what would you get if you wanted:
or whatever the syntax would be?
If it was in alphabetical order, you'd be all set, but what it if
wasn't? It would be pretty cool if you could get an alphabetical slice.
