Failed to install

Win10, Py3.6.10  and WinPy3.7.7.

Try it again. I had to refactor it to work with Python < 3.8

That's the new assignment expression for python >=3.8, and they're awesome. I had to remove all those from the library to make it work with your version, but I think you can refactor that example script to make it work. You should consider upgrading your python interpreter to the latest version.  :)

Не могу. Слишком много пакетов завязаны на 3.7.7 и 3.6.10. 

Просто подскажите чем или как заменить, если возможно. Если нет, не проблема.

Я не знаток Питона. Мой язык R/ 

Удачи.

Vladimir Perervenko:

I can not. Too many packages are tied to 3.7.7 and 3.6.10. 

Just tell me what or how to replace, if possible. If not, no problem.

I'm not a Python expert. My language is R / 

Good luck.
