skrf.io.general.read_all

skrf.io.general.read_all(dir='.', sort=True, contains=None, f_unit=None, obj_type=None, files=None, recursive=False)[source]

Read all skrf objects in a directory.

Attempts to load all files in dir, using read(). Any file that is not readable by skrf is skipped. Optionally, simple filtering can be achieved through the use of contains argument.

Parameters:

dir (str or Path, optional) – the directory to load from, default ‘.’
sort (boolean, default is True) – filenames sorted by https://docs.python.org/3/library/stdtypes.html#list.sort without arguments
contains (str, optional) – if not None, only files containing this substring will be loaded
f_unit (['hz','khz','mhz','ghz','thz']) – for all Network objects, set their frequencies’s f_unit
obj_type (str) – Name of skrf object types to read (ie ‘Network’)
files (list, optional) – list of files to load, bypasses dir parameter.
recursive (bool, optional) – If True, search in the specified directory and all other nested directories

Returns:

out – dictionary containing all loaded skrf objects. keys are the filenames without extensions, and the values are the objects

Return type:

dictionary
