Parameters ---------- filepath_or_buffer : str, path object or file-like object Any valid string path is acceptable. The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. A local file could be: ``file://localhost/path/to/table.sas``. If you want to pass in a path object, pandas accepts any ``os.PathLike``. By file-like object, we refer to objects with a ``read()`` method, such as a file handler (e.g. via builtin ``open`` function) or ``StringIO``. format : str {'xport', 'sas7bdat'} or None If None, file format is inferred from file extension. If 'xport' or 'sas7bdat', uses the corresponding format. index : identifier of index column, defaults to None Identifier of column that should be used as index of the DataFrame. encoding : str, default is None Encoding for text data. If None, text data are stored as raw bytes. chunksize : int Read file `chunksize` lines at a time, returns iterator. iterator : bool, defaults to False If True, returns an iterator for reading the file incrementally. Returns ------- DataFrame if iterator=False and chunksize=None, else SAS7BDATReader or XportReader NzVIf this is a buffer object rather than a string name, you must specify a format stringz.xptZxportz .sas7bdatZsas7bdatz"unable to infer format of SAS filer) XportReader)rrr)SAS7BDATReaderzunknown SAS format) r isinstancestr ValueErrorlowerendswithZpandas.io.sas.sas_xportrZpandas.io.sas.sas7bdatr rr) rrrrrrZbuffer_error_msgfnamerreaderr datar r rr6s2*       ).....).....)NNNNF)rabcrrtypingrrrrZpandas._typingrr Zpandas.io.commonr Zpandasr r r"intboolrr r r rs6
