# pandas.util.hash_pandas_object

pandas.util.hash_pandas_object(obj, index=True, encoding='utf8', hash_key='0123456789123456', categorize=True)

  Return a data hash of the Index/Series/DataFrame.

  Parameters:
    objIndex, Series, or DataFrame
    indexbool, default True

      Include the index in the hash (if Series/DataFrame).

    encodingstr, default ‘utf8’

      Encoding for data & key when strings.

    hash_keystr, default _default_hash_key

      Hash_key for string key to encode.

    categorizebool, default True

      Whether to first categorize object arrays before hashing. This is more efficient when the array contains duplicate values.

  Returns:
    Series of uint64, same length as the object
