Thanks for your response!  Yes, the problem was a circular definition.  I still 
have much to learn about Python...

[issue30518] Import type aliases from another module

John Jackson added the comment:

I just found out that the problem is even worse.  While PyCharm accepts the 
syntax below, I still can't compile 'Blocks'.

[issue30518] Import type aliases from another module

2017-05-30 Thread John Jackson 

New submission from John Jackson:

I have a 'base' module where I define some type aliases, such as:

from typing import List, Tuple
Block = [int, Tuple[int]]
Blocks = List[Block]
Tags = List[str]

I would like to import these aliases into other modules so that the 'base' 
module provides the definitive alias.

Currently, if I attempt to import the type aliases using:

from base_module import Tags, Blocks

Pycharm shows no error, but when I attempt to execute the code I get the error:

ImportError: cannot import name 'Tags'

I see that there has been some discussion related to this in 2015, but I can't 
find any documentation saying that something like this has been implemented.
