Tkinter is a Python wrapper for Tcl/Tk providing a cross-platform GUI toolkit. On Windows, it comes bundled with Python; on other operating systems, it can be installed. The set of available widgets is smaller than in some other toolkits, but since Tkinter widgets are extensible, many of the missing compound widgets can be created using the extensibility, such as combo box and scrolling pane.
IDLE, Python's Integrated Development and Learning Environment, is written using Tkinter and is often distributed with Python. You can learn about features of Tkinter by playing around with menus and dialogs of IDLE. For instance, Options > Configure IDLE.. dialog shows a broad variety of GUI elements including tabbed interface. You can learn about programming using Tkinter by studying IDLE source code, which, on Windows, is available e.g. in C:Program FilesPython27Libidlelib.
Python 3: The examples on this page are for Python 2. In Python 3, what was previously module Tkinter is tkinter, what was tkMessageBox is messagebox, etc.
