1,

python自带了curses库

http://coolshell.cn/articles/677.html

import curses 
 
myscreen = curses.initscr()
 
myscreen.border(0)
myscreen.addstr(12, 25, "Python curses in action!")
myscreen.refresh()
myscreen.getch()
 
curses.endwin()

#!/usr/bin/env python
 
from os import system
import curses
 
def get_param(prompt_string):
     screen.clear()
     screen.border(0)
     screen.addstr(2, 2, prompt_string)
     screen.refresh()
     input = screen.getstr(10, 10, 60)
     return input
 
def execute_cmd(cmd_string):
     system("clear")
     a = system(cmd_string)
     print ""
     if a == 0:
          print "Command executed correctly"
     else:
          print "Command terminated with error"
     raw_input("Press enter")
     print ""
 
x = 0
 
while x != ord('4'):
     screen = curses.initscr()
 
     screen.clear()
     screen.border(0)
     screen.addstr(2, 2, "Please enter a number...")
     screen.addstr(4, 4, "1 - Add a user")
     screen.addstr(5, 4, "2 - Restart Apache")
     screen.addstr(6, 4, "3 - Show disk space")
     screen.addstr(7, 4, "4 - Exit")
     screen.refresh()
 
     x = screen.getch()
 
     if x == ord('1'):
          username = get_param("Enter the username")
          homedir = get_param("Enter the home directory, eg /home/nate")
          groups = get_param("Enter comma-separated groups, eg adm,dialout,cdrom")
          shell = get_param("Enter the shell, eg /bin/bash:")
          curses.endwin()
          execute_cmd("useradd -d " + homedir + " -g 1000 -G " + groups + " -m -s " + shell + " " + username)
     if x == ord('2'):
          curses.endwin()
          execute_cmd("apachectl restart")
     if x == ord('3'):
          curses.endwin()
          execute_cmd("df -h")
 
curses.endwin()

2,pip install urwid

urwid 功能及例子很丰富，用法更传统

3,pip install npyscreen

npyscreen最近还有更新，而用法基本是对象化，跟c#/java更接近
