These are both invalid type aliases (I have no idea why PyCharm does not flag them, you could report this at PyCharm issue tracker). I am not sure what exactly you want. If you want a list of either integers or tuples of integers, then you should write for example: Block = Union[int, Tuple[int, ...]] Blocks = List[Block] Concerning import, this is definitely not a problem with aliases. What I have noticed is that you write "I have a 'base' module ..." and then "from base_module import ...", if you have a module named base.py, then you should write: from base import Blocks, Tags Or maybe you just have an import cycle... ---------- nosy: +levkivskyi _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30518> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
