That's why the padding leads to a new data array that has the same dimension name as the original one but no coordinates.

We can set the coordinates explicitly using the `coords` attribute of the DataArray after padding. Check this example:
```
import numpy as np
import xarray as xr

da = xr.DataArray(np.arange(9), dim='x')
padded_da = da.pad({'x': (0, 1)}, 'constant')
padded_da.coords['x'] = np.arange(padded_da.shape[0])
print(padded_da)

<xarray.DataArray (x: 3)>
array([ 0.,  1., nan])
Coordinates:
  * x        (x) int64 0 1 2
```

Hopefully this helps!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1188523721
