skrf.io.general.read_all¶

skrf.io.general.read_all(dir='.', 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, optional) – the directory to load from, default ‘.’
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
