# scipy.io.readsav

`scipy.io.``readsav`(file_name, idict=None, python_dict=False, uncompressed_file_name=None, verbose=False)

  Read an IDL .sav file

  Parameters : | file_name : str Name of the IDL save file. idict : dict, optional Dictionary in which to insert .sav file variables python_dict : bool, optional By default, the object return is not a Python dictionary, but a case-insensitive dictionary with item, attribute, and call access to variables. To get a standard Python dictionary, set this option to True. uncompressed_file_name : str, optional This option only has an effect for .sav files written with the /compress option. If a file name is specified, compressed .sav files are uncompressed to this file. Otherwise, readsav will use the `tempfile` module to determine a temporary filename automatically, and will remove the temporary file upon successfully reading it in. verbose : bool, optional Whether to print out information about the save file, including the records read, and available variables.
  Returns : | idl_dict : AttrDict or dict If python_dict is set to False (default), this function returns a case-insensitive dictionary with item, attribute, and call access to variables. If python_dict is set to True, this function returns a Python dictionary with all variable names in lowercase. If idict was specified, then variables are written to the dictionary specified, and the updated dictionary is returned.
