The curses Module

(Unix only, Optional) The curses module gives you better control of the text terminal window, in a terminal-independent way. Example 12-7 shows its use.

Example 12-7. Using the curses Module

File: curses-example-1.py

import curses

text = [
 "a very simple curses demo",
 "",
 "(press any key to exit)"
]

# connect to the screen
screen = curses.initscr()

# setup keyboard
curses.noecho() # no keyboard echo
curses.cbreak() # don't wait for newline

# screen size
rows, columns = screen.getmaxyx()

# draw a border around the screen
screen.border()

# display centered text
y = (rows - len(text)) / 2

for line in text:
 screen.addstr(y, (columns-len(line))/2, line)
 y = y + 1

screen.getch()

curses.endwin()
