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.sas7bdat``. 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 Examples -------- >>> df = pd.read_sas("sas_data.sas7bdat") # doctest: +SKIP 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,r.)SAS7BDATReaderzunknown SAS format) r isinstancestr ValueErrorlowerreprpandas.io.sas.sas_xportr=pandas.io.sas.sas7bdatr>r) r/r)r*r+r,r-r.buffer_error_msgfnamer=readerr>rrrr6RsL4      $)r/r0r)r1r*r2r+r1r,r3r-r4r.r rr)r/r0r)r1r*r2r+r1r,rr-r4r.r rr8)r/r0r)r1r*r2r+r1r,rr-r4r.r rr8)r( __future__rtypingrrrpandas.util._decoratorsrpandas.core.shared_docsrpandas.io.commonrcollections.abcr typesr pandas._typingr r r pandasrrr6rrrrsH
