Apply func(self, *args, **kwargs)
This method replicates the pandas method of the same name.
func (callable()
) – function to apply to this xarray object (Dataset/DataArray). args
, and kwargs
are passed into func
. Alternatively a (callable, data_keyword)
tuple where data_keyword
is a string indicating the keyword of callable
that expects the xarray object.
*args – positional arguments passed into func
.
**kwargs – a dictionary of keyword arguments passed into func
.
object (T
) – the return type of func
.
Notes
Use .pipe
when chaining together functions that expect xarray or pandas objects, e.g., instead of writing
f(g(h(dt), arg1=a), arg2=b, arg3=c)
You can write
(dt.pipe(h).pipe(g, arg1=a).pipe(f, arg2=b, arg3=c))
If you have a function that takes the data as (say) the second argument, pass a tuple indicating which keyword expects the data. For example, suppose f
takes its data as arg2
:
(dt.pipe(h).pipe(g, arg1=a).pipe((f, "arg2"), arg1=a, arg3=c))
