@Eternal1 @TheRedDevil Thanks for your comments. The article was actually targeted to editors and NOT IDEs. Yes, PyCharm is very popular, but, wasn’t mentioned here since it is considered an IDE. In order to see the difference between a text editor and an IDE, please check the first section of my post, here: http://www.sitepoint.com/ides-rubyists-use/
Please let me know should you have any questions.
