Install Python development environment on Windows 10

How to install on Windows here

important point

As of October 13, 2020, the Python 3.9 version of Miniconda has not yet been released. So this article uses Python 3.8 series.

This article will be revised as Miniconda supports 3.9. However, I think that the installation method will not change even if it becomes 3.9.
