"A certain class of Python applications works best with an interactive user interface without the overhead or complexity of a graphical environment. For interactive text-mode programs (under Linux/UNIX), for example, the ncurses library, wrapped in Python's standard curses module, is just what you need. In this article, David Mertz discusses the use of curses in Python. He illustrates the curses environment using sample source code from a front-end to the Txt2Html program."

"The curses library (ncurses) provides a terminal-independent method of controlling character screens. curses is a standard part of most UNIX-like systems, including Linux, but has also been ported to Windows and other systems. Curses programs will run on text-only systems and within xterm's and other windowed console sessions, which helps make these applications very portable."

"Python's standard curses provides a basic interface to the common features of the "glass teletype," as the CRT was known in the 1970s when the original curses library was created. There are a number of ways to bring greater sophistication to interactive text-mode programs written in Python. These fall into two categories."
