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.
Examples -------- >>> from os.path import dirname, join as pjoin >>> import scipy.io as sio >>> from scipy.io import readsav
Get the filename for an example .sav file from the tests/data directory.
>>> data_dir = pjoin(dirname(sio.__file__), 'tests', 'data') >>> sav_fname = pjoin(data_dir, 'array_float32_1d.sav')
Load the .sav file contents.
>>> sav_data = readsav(sav_fname)
Get keys of the .sav file contents.
>>> print(sav_data.keys()) dict_keys('array1d')
Access a content with a key.
>>> print(sav_data'array1d') 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.
