Remove the module named module_name from sys.modules and delete any byte-compiled files of the module. This function imports and returns a fresh copy of the named Python module by removing the named module from sys.modules before doing the import. Note that unlike reload, the original module is not affected by this operation. fresh is an iterable of additional module names that are also removed from the sys.modules cache before doing the import. blocked is an iterable of module names that are replaced with None in the module cache during the import to ensure that attempts to import them raise ImportError. The named module and any modules named in the fresh and blocked parameters are saved before starting the import and then reinserted into sys.modules when the fresh import Attribution: Adapted from Python Documentation under PSF-2.0.
