How to configure a Python development environment using VScode

Software preparation

First, we must download the Python installation package and the VScode installation package.

You can choose the version that suits you and download it.
I am running Windows 10 64-bit operating system, so I downloaded Python with the latest 64-bit version, and VSco'de downloaded the latest 64-bit version.
Here I recommend that you choose Python3 instead of Python2.7, but this tutorial will still apply even if you download Python2.7.
