pandas.util. hash_pandas_object(obj, index=True, encoding='utf8', hash_key=None, categorize=True)[source]¶

Return a data hash of the Index/Series/DataFrame

New in version 0.19.2.

Parameters:	index : boolean, default True include the index in the hash (if Series/DataFrame) encoding : string, default ‘utf8’ encoding for data & key when strings hash_key : string key to encode, default to _default_hash_key categorize : bool, default True Whether to first categorize object arrays before hashing. This is more efficient when the array contains duplicate values. New in version 0.20.0.
Returns:	Series of uint64, same length as the object
