methods
-
resolve_mapping_to_dict(mapping, source)- move values fromsourceinto a returned dict, usingmappingfor paths and returned keys.from transmogrifydict import resolve_mapping_to_dict mapping = { 'a': 'd', 'b': 'e', 'c': 'f' } source = { 'd': 1, 'e': 2, 'f': 3 } resolve_mapping_to_dict(mapping, source) # { # 'a': 1, # 'b': 2, # 'c': 3, # }
-
resolve_path_to_value(source, path)- fetch a value out ofsourceusingpathas the pointer to the desired value. see docstring for path string formats.from transmogrifydict import resolve_path_to_value source = { 'd': 1, 'e': 2, 'f': 3 } found, value = resolve_path_to_value(source, 'e') print((found, value)) # (True, 2)
