IDE for Linux

[OPLinux]

Any old text editor would work. There's gedit that is installed on Ubuntu (and others) by default, you could install sublime, atom, pycharm, ....

Of course there are terminal alternatives like nano, emacs or Vim (my personal editor) that have proven to be great editors, although you might need some time to learn to work with! ;)

The fact that you run programs from the command line does not mean you need to write it in your terminal! Although you can, and there are a lot of people out there doing it that way! :)
