Curses print characters as typed

问题

Using python I am wanting to have the characters printed out as i type, this is easy in java script, but I am not understanding how to use the curses module, this is the code that I tried but it did not work.

import curses
stdscr = curses.initscr()
curses.echo()
curses.cbreak()
a = raw_input()
print a 
stdscr.refresh()

could you please explain how i use this part of the curses module.

If you just want to get the user input and make the characters printed out as they are typed, there's not much to do :

import          curses

stdScr = curses.initscr()
myInput = stdScr.getstr()
curses.endwin()
print(myInput.decode('utf-8'))

Here, you just initialize the curses module by calling curses.initscr(). It gives you the stdScr and you just have to call the getstr() method of stdScr (which is actually a curses.window object) which will give you the user input printing the characters as they are typed.

I don't know if you've already checked this out, but it's very clear : http://docs.python.org/3.3/library/curses.html

Have fun ! (curses is an awesome module !)
