Parameters ---------- filepath_or_buffer : str, path object, or file-like object String, path object (implementing ``os.PathLike[str]``), or file-like object implementing a binary ``read()`` function. 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``. 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. .. versionchanged:: 1.2 ``TextFileReader`` is a context manager. iterator : bool, defaults to False If True, returns an iterator for reading the file incrementally. .. versionchanged:: 1.2 ``TextFileReader`` is a context manager. {decompression_options} 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.xptxportz .sas7bdatsas7bdatz2unable to infer format of SAS file from filename: r) XportReader)r,r.r/r3)SAS7BDATReaderzunknown SAS format) r isinstancestr ValueErrorlowerreprpandas.io.sas.sas_xportr>pandas.io.sas.sas7bdatr?r) r(r*r,r.r/r1r3buffer_error_msgfnamer>readerr?rrrr5QsL0      $)......)r(r)r*r+r,r-r.r+r/r0r1r2r3rrr)r(r)r*r+r,r-r.r+r/rr1r2r3rrr7)NNNNFr;)r(r)r*r+r,r-r.r+r/rr1r2r3rrr7)r& __future__rabcrrtypingrrrpandas._typingrr r pandas.util._decoratorsr r pandas.core.shared_docsr pandas.io.commonrpandasrrr5rrrrsH
