   ```
   import pyarrow as pa
   import pandas as pd
   df = pd.DataFrame({'year': [2020, 2022, 2019, 2021],
                      'n_legs': [2, 4, 5, 100],
                      'animals': ["Flamingo", "Horse", "Brittle stars", None]})
   table = pa.Table.from_pandas(df)
   
   ```
   `df.loc[df["animals"].isnull(), "animals"] = "new_value" # how do we perform this in pyarrow?`
