I like Ninja-Ide, because it is ideal for working with the python language, where it provides facilities for ideation tabs, something very important in Python, command highlighting, a large gallery of plug-ins that offers a lot of code complement, which it facilitates and reduces the programmer's effort in developing routines, since many of them are made and provided by the Pyrthon community. It also facilitates the organization of the files through its Project Tabs where you can create, delete or export files. The programmer can also relocate and activate the tool tabs he needs and in the place of the programming environment he wants.

It's free and also works on ubuntu or other linux

What I like the most is that it is a lightweight IDE, the code is displayed in colors according to whether they are variables, functions... You can compile the code without relying on the Windows CMD, plugins can be installed, some necessary like the debugger, it has keyboard shortcuts that help a lot, it is a cross-platform program that can be used on Linux, Windows, and OS X. It allows you to manage projects, save descriptions and information about them, and allows the user to perform tasks related to file management within the IDE itself. You can easily see all the functions, classes, and attributes in the current program.
