Answer 1

默认情况下，回显处于启用状态。下线需要调用noecho。

#!/usr/bin/env python

import curses
import curses.textpad as textpad

try:
    mainwindow = curses.initscr()
    # Some curses-friendly terminal settings
    curses.cbreak(); mainwindow.keypad(1); curses.noecho()
    textpad.Textbox(mainwindow).edit()
finally:
    # Reverse curses-friendly terminal settings
    curses.nocbreak(); mainwindow.keypad(0); curses.echo()
    curses.endwin()

(该脚本已在Python 2.7上进行了测试)。我建议你去看看curses programming page。

Answer 2

使用curses.noecho()：

import curses
import curses.textpad as textpad

try:
    mainwindow = curses.initscr()
    curses.noecho()
    textpad.Textbox(mainwindow).edit()
finally:
    curses.endwin()
