383945783 MDU6SXNzdWUzODM5NDU3ODM= 2568 Xarray equivalent of np.place or df.map(mapping)? 15331990 closed 0     11 2018-11-24T00:33:11Z 2022-04-18T15:51:57Z 2022-04-18T15:51:57Z CONTRIBUTOR      

```python

numpy version

x = np.array([0, 1]) np.place(x, x == 0, 1)

pandas version

pd.Series([0, 1]).map({0: 1, 1: 1})

current workaround

ds = xr.Dataset({'test': [0, 1]}) np.place(ds['test'].values, ds['test'].values == 0, 1)

```

Problem description

Is there a built in method to map values like 0 to 1?

Expected Output

returns [1, 1]
