How To Convert DataFrame To Pickle File?
How To Convert DataFrame To Pickle File? Table Of Contents: Syntax ‘isna( )’ Method In Pandas. Examples ‘isna( )’ Method. (1) Syntax: DataFrame.to_pickle(path, compression=’infer’, protocol=5, storage_options=None) Description: Convert DataFrame To Pickle File. Parameters: path: str, path object, or file-like object – String, path object (implementing os.PathLike[str]), or file-like object implementing a binary write() function. File path where the pickled object will be stored. compression: str or dict, default ‘infer’ – For on-the-fly compression of the output data. If ‘infer’ and ‘path’ is path-like, then detect compression from the following extensions: ‘.gz’, ‘.bz2’, ‘.zip’, ‘.xz’, ‘.zst’, ‘.tar’, ‘.tar.gz’, ‘.tar.xz’ or ‘.tar.bz2’ (otherwise no compression).
