pandas.Series.to_pickle

Series.to_pickle(path, compression='infer', protocol=4) [source]

Pickle (serialize) object to file.

Parameters:

path : str File path where the pickled object will be stored. compression : {‘infer’, ‘gzip’, ‘bz2’, ‘zip’, ‘xz’, None}, default ‘infer’ A string representing the compression to use in the output file. By default, infers from the file extension in specified path. New in version 0.20.0. protocol : int Int which indicates which protocol should be used by the pickler, default HIGHEST_PROTOCOL (see [R27] paragraph 12.1.2). The possible values for this parameter depend on the version of Python. For Python 2.x, possible values are 0, 1, 2. For Python>=3.0, 3 is a valid value. For Python >= 3.4, 4 is a valid value. A negative value for the protocol parameter is equivalent to setting its value to HIGHEST_PROTOCOL. [R27] https://docs.python.org/3/library/pickle.html New in version 0.21.0.
