"from typing import Type" (works in Debian, not working under Arch) #1838
Description
I installed typing via pip3 in both my Debian and Arch environments, and see this:
Under Debian:
$ pip3 freeze | grep typing
typing==3.5.2.2
$ python3
Python 3.4.2 (default, Oct 8 2014, 13:14:40)
[GCC 4.9.1] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from typing import Type
>>>
Under Arch:
$ pip3 freeze | grep typing
typing==3.5.2.2
$ python3
Python 3.5.1 (default, Mar 3 2016, 09:29:07)
[GCC 5.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from typing import Type
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'Type'
>>>
Have I messed up or is there some difference due to 3.4 -> 3.5?
P.S. In case there's a way around it - I use Type, because I have annotated code like this:
U = TypeVar('U', int, float)
def GetRange(newModule: Module, lineNo: int, nodeWithMinAndMax: Element, valueType: Type[U]) -> Tuple[U, U]:
...
rangel = valueType(mmin)
rangeh = valueType(mmax)
return (rangel, rangeh)
...so I can create the appropriate type at runtime in my AST.
