What happened:

accessing variable attribute seems to work but also throws an AttributeError:

AttributeError: 'Variable' object has no attribute 'variable'

What you expected to happen:

According to https://xarray.pydata.org/en/stable/terminology.html all DataArrays should have "an underlying variable that can be accessed via arr.vairable", so I tried that out and got the error.

Minimal Complete Verifiable Example:

Using the example code from the docs: python data = xr.DataArray(np.random.randn(2, 3), dims=('x', 'y'), coords={'x': [10, 20]}) data.variable

Environment: Python 3.7 on Kubuntu 20.04 using Brave browser in Jupyterlab, up-to-date conda env.
