equals

UnitsAwareDataArray.equals(other: Self) → bool

True if two DataArrays have the same dimensions, coordinates and values; otherwise False.

DataArrays can still be equal (like pandas objects) if they have NaN values in the same locations.

This method is necessary because v1 == v2 for DataArray does element-wise comparisons (like numpy.ndarrays).

Parameters:

other (DataArray) – DataArray to compare to.

Returns:

equal – True if the two DataArrays are equal.

Return type:

bool

Examples

>>> a = xr.DataArray([1, 2, 3], dims="X")
>>> b = xr.DataArray([1, 2, 3], dims="X", attrs=dict(units="m"))
>>> c = xr.DataArray([1, 2, 3], dims="Y")
>>> d = xr.DataArray([3, 2, 1], dims="X")
>>> a
<xarray.DataArray (X: 3)> Size: 24B
array([1, 2, 3])
Dimensions without coordinates: X
>>> b
<xarray.DataArray (X: 3)> Size: 24B
array([1, 2, 3])
Dimensions without coordinates: X
.. attribute:: units

m

>>> c
<xarray.DataArray (Y: 3)> Size: 24B
array([1, 2, 3])
Dimensions without coordinates: Y
>>> d
<xarray.DataArray (X: 3)> Size: 24B
array([3, 2, 1])
Dimensions without coordinates: X

>>> a.equals(b)
