xarray.core.accessor_str.StringAccessor

class xarray.core.accessor_str.StringAccessor(obj)

Vectorized string functions for string-like arrays.

Similar to pandas, fields can be accessed through the .str attribute for applicable DataArrays.

>>> da = xr.DataArray(["some", "text", "in", "an", "array"])
>>> da.str.len()
<xarray.DataArray (dim_0: 5)>
array([4, 4, 2, 2, 5])
Dimensions without coordinates: dim_0

__init__(obj)

Initialize self. See help(type(self)) for accurate signature.
