# pandas.DataFrame.to_feather

DataFrame.to_feather(path, **kwargs)

  Write a DataFrame to the binary Feather format.

  Parameters:
    pathstr, path object, file-like object

      String, path object (implementing `os.PathLike[str]`), or file-like object implementing a binary `write()` function. If a string or a path, it will be used as Root Directory path when writing a partitioned dataset.

    **kwargs

      Additional keywords passed to `pyarrow.feather.write_feather()`. This includes the compression, compression_level, chunksize and version keywords.

  Notes

  This function writes the dataframe as a feather file. Requires a default index. For saving the DataFrame with your custom index use a method that supports custom indices e.g. to_parquet.

  Examples

      >>> df = pd.DataFrame([[1, 2, 3], [4, 5, 6]])
      >>> df.to_feather("file.feather")
