PySimpleGUI

0. Virtual environment preparation (venv)

I didn't want to pollute the global environment, so I decided to create a virtual environment with venv and work there.

Virtual environment startup

$ python -m venv myvenv
$ cd myvenv/
$ source bin/activate
(myvenv)$ pip list
pip (7.1.2)
setuptools (18.2)

            [sg.Button('Ok'), sg.Button('Cancel')] ]

Summary

Unlike web applications that use a browser, I felt that it was good because I could code with an awareness of "event loops".
