Chapter 17. Tkinter GUIs
Most professional client-side applications interact with the user through a graphical user interface (GUI). A GUI is programmed through a toolkit, which is a library that supplies controls (also known as widgets), visible objects such as buttons, labels, text entry fields, and menus. A GUI toolkit lets you compose controls into a coherent whole, display them on-screen, and interact with the user, receiving input via keyboard and mouse.
Python gives you a choice among many GUI toolkits. Some are platform-specific, but most are cross-platform, supporting at least Windows and Unix-like platforms and often the Mac as well. http://wiki.python.org/moin/GuiProgramming lists dozens of GUI toolkits for Python. The most popular Python GUI toolkit today is probably wxPython (http://www.wxpython.org/), but the one distributed with Python itself is Tkinter.
Tkinter is an object-oriented Python wrapper around the cross-platform toolkit Tk, which is also used with other scripting languages such as Tcl (for which it was originally developed), Ruby, and Perl. Tkinter, like the underlying Tcl/Tk, runs on Windows, Macintosh, and Unix-like platforms. On Windows, the standard Python distribution also includes, as well as Tkinter itself, the Tcl/Tk library needed to run Tkinter. On other platforms, you may have to obtain and install Tcl/Tk separately (you may also have to install or reinstall Python after Tcl/Tk, depending on the Python distribution’s details).
