python - Python 诅咒中的 addstr 延迟

Question

我正在研究 AI，我正在使用 Curses，我希望能够添加一条消息，等待五秒钟然后绘制另一条消息。

下面是我要修复的部分

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import curses
import time

screen = curses.initscr()
curses.noecho()
curses.curs_set(0)
screen.keypad(1)

screen.addstr("This is a Sample Curses Script\n\n")
screen.addstr("This is a Sample Curses Script\n\n")
time.sleep(5)
screen.addstr("This is a Sample Curses Script\n\n")
while True:
   event = screen.getch()
   if event == ord("q"): break

curses.endwin()

Answer 1

来自官方指南：

在窗口上放上你想要的东西之后，当你想让窗口覆盖的终端部分看起来像它时，你必须调用 refresh()。

因此，这样更改您的代码：

import curses
import time

screen = curses.initscr()
curses.noecho()
curses.curs_set(0)
screen.keypad(1)

screen.addstr("This is a Sample Curses Script\n\n")
screen.addstr("This is a Sample Curses Script\n\n")
screen.refresh()
time.sleep(5)
screen.addstr("This is a Sample Curses Script\n\n")
screen.refresh()
while True:
    event = screen.getch()
    if event == ord("q"): break

curses.endwin()
