IDLE in action under Ubuntu: shell with highlights settings
IDLE (short for Integrated Development and Learning Environment) is an integrated development environment for Python, which has been bundled with the default implementation of the language since 1.5.2b1. It is packaged as an optional part of the Python packaging with many Linux distributions. It is completely written in Python and the Tkinter GUI toolkit (wrapper functions for Tcl/Tk).
IDLE is intended to be a simple IDE and suitable for beginners, especially in an educational environment. To that end, it is cross-platform, and avoids feature clutter.
According to the included README, its main features are:
Multi-window text editor with syntax highlighting, autocompletion, smart indent and other.
Python shell with syntax highlighting.
Integrated debugger with stepping, persistent breakpoints, and call stack visibility.
Author Guido van Rossum says IDLE stands for "Integrated Development and Learning Environment", and since Van Rossum named the language Python after the British comedy group Monty Python, the name IDLE was probably also chosen partly to honor Eric Idle, one of Monty Python's founding members.

^Subject: IDLE 0.1 -- a Python IDEArchived 2018-09-25 at the Wayback Machine, By Guido van Rossum - 16 Nov 1998 - comp.lang.python, At the conference I mentioned a few times that I was working on a Tkinter-based IDE for Python. I've decided to use the paradigm "release early and often" for this piece of software (especially since I don't expect I'll have much time to work on it), so version 0.1 (essentially a dump of my directory) is now sitting in the contrib directory ftp.python.org.
