GUI Python3 vs GUI Shell Scripting

GUI Python 3 vs GUI (Linux) Shell Scripting

================================

As a PHP/JS Web Developer I study in my free time Linux topics online or in e-books… Also started study Python 3… As I mention Python 3 and Linux Shell Scripts provide some commands for creating GUIs windows[programs with GUI instead of the traditional CLI…  text mode programs]… In this post I focus on GUIs in Python 3 vs Shell Scripting GUIs…

Shell Scripting at first exist on Unix/Linux/MacOS OSs… (mainly Linux) but Python can installed in any OS including Windows 10….

In this article I use Linux Ubuntu Studio 18.10 for the demonstrations – I like using Ubuntu Studio rather Ubuntu or Fedora… because Ubuntu Studio come from Canonical too, and has preinstalled many free programs for Graphic Design, Video/Audio Edit, Photography, Publishing Ebooks, etc Tools… that’s I feel Not needed change OS to do these other essential Tasks for my work like edit an image etc… !!!

 

 

Coming Soon !!!
