(This is necessary to distinguish between a submodule and an attribute when there is a conflict.). If the dotted path does not include a colon and the final item is not a valid module, importing as an attribute rather than a submodule will be attempted automatically. So, for example, the following values of `dotted_path` result in the following returned values: * 'collections': <module 'collections'> * 'collections.abc': <module 'collections.abc'> * 'collections.abc:Mapping': <class 'collections.abc.Mapping'> * `collections.abc.Mapping`: <class 'collections.abc.Mapping'> (though this is a bit slower than the previous line) An error will be raised under any of the following scenarios: * `dotted_path` contains more than one colon (e.g., 'collections:abc:Mapping') * the substring of `dotted_path` before the colon is not a valid module in the environment (e.g., '123:Mapping') * the substring of `dotted_path` after the colon is not an attribute of the module (e.g., 'collections:abc123') r )� import_module�:� z5Import strings should have at most one ':'; received z<Import strings should have a nonempty module name; received �.� zNo module named Nzcannot import name z from ) � importlibr& �strip�split�lenr" �ModuleNotFoundError�rsplitr! �getattr�AttributeError) r% r& � components� module_path�moduler# Zmaybe_module_pathZmaybe_attribute� attributer r r r!
