Python/winrt support for python 3.8 version

[pbvinoth]

We have module called python/winrt which will be helpful to access the windows runtime apis.

While trying to install the module facing below error.

C:\Users\vpbx\Desktop>pip install winrt
ERROR: Could not find a version that satisfies the requirement winrt (from versions: none)
ERROR: No matching distribution found for winrt

https://pypi.org/project/winrt/

My all Prerequisites are satisfied but still facing the error.
Windows 10, October 2018 Update or later.
Python for Windows, version 3.7 or later
pip, version 19 or later

Will winrt support python3.8 version, if not please explain about the current status that we can expect on python 3.8 version.

it doesn't specifically say that it supports python 3.8 (shows latest as 3.7) and also states cpython requirement.
also under known issues:

This release of the Python/WinRT does not support WinRT composable types. This includes most of the classes in the Windows.UI.Composition and Windows.UI.Xaml namespaces. These namespaces are excluded from Python/WinRT.
Note, a few methods in other namespaces reference types in these namespaces. For example, MediaPlayerSurface is in the Windows.Media.Playback namespace but has properties that return types in the Windows.UI.Composition namespace. While these properties are available to Python, accessing them is not supported at this time.

I've had good success installing packages which specify 3.7 on 3.8, but this package might be a bit more fussy.
Best bet is to contact the authoe and ask. (Kenny Kerr Microsoft)

There is an Issue rapport here.

There are several way you use 3.7 and don't touch your Python 3.8 installation.
Just install python 3.7 from here,do not add to Environment Variables Path.
Then install with py -3.7 -m pip install winrt.

E:\div_code
λ py -3.7 -m pip install winrt

I still have Python 3.8 as main version in path,but using py can access all other version.

E:\div_code
λ python -V
Python 3.8.3

E:\div_code
λ pip -V
pip 20.1.1 from c:\python38\lib\site-packages\pip (python 3.8)

Using Anaconda example the smaller version Miniconda
This is a stand alone version that are Python 3.7,so here can just install normal with pip.
Do this from Scripts where pip are.

G:\mini_conda37\Scripts
λ pip -V
pip 20.0.2 from G:\mini_conda37\lib\site-packages\pip (python 3.7)

G:\mini_conda37\Scripts
λ pip install winrt

With conda can also create virtual environment for a specific Python version wanted.

conda create -n myenv python=3.7
