Python诅咒中的addstr延迟

Question

我正在使用AI，并且正在使用Curses，所以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。

以下是我要修复的部分

#!/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

从官方指南 ：

在窗口上放置了所需的内容之后，当要使窗口覆盖的终端部分看起来像它时，必须调用refresh（）。

因此，可以这样更改代码：

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()
