        name (str): the name of the module to import, e.g. sys
        modules (str): the modules to import, use None for everything
        exception (Exception): the exception to catch, e.g. ImportError

        `globals_`: the `globals()` method (in case you need a different scope)
        level (int): the level to import from, this can be used for
