Concise way to filter data in xarray

Question

I need to apply a very simple \'match statement\' to the values in an xarray array:

1. Where the value > 0, make 2
2. Where the value == 0, make 0
3. Wher

Answer 1

xarray now supports .where(condition, other), so this is now valid:

result = date_by_items.where(date_by_items > 0, 2)
