Curses.ADDSTR不会输出到控制台

我最近通过py -m pip安装Windows-curses在高架命令提示符中运行的Windows-curses模块在我的计算机上安装了模块。

我编写了以下代码以测试它是否正常工作。如果正确运行，则应将字符串打印到控制台。但是，什么都没有发生 - 即终端保持空白，没有显示字符。

#initialise curses
import curses
stdscr=curses.initscr()
curses.noecho()
curses.cbreak()
stdscr.keypad(True)

#write text
stdscr.addstr(0,0,'test')

#loop program so the terminal does not close
while 1:
    pass

我尝试将addstr拨打到While循环中，并使用包装器，但都没有解决问题。发生了什么，我该如何解决这个问题？提前致谢！

I've recently installed the windows-curses module on my machine, via py -m pip install windows-curses run in an elevated command prompt.

I wrote the following code to test if it was working correctly. If it runs correctly, it should print the string test to the console. However, nothing happens - i.e the terminal remains blank, with no characters displayed.

#initialise curses
import curses
stdscr=curses.initscr()
curses.noecho()
curses.cbreak()
stdscr.keypad(True)

#write text
stdscr.addstr(0,0,'test')

#loop program so the terminal does not close
while 1:
    pass

I've tried putting the addstr call inside the while loop, as well as using the wrapper, but neither resolved the issue.
What's going on, and how can I resolve this issue? Thanks in advance!

您必须刷新屏幕。当您要求输入时，例如window.getch（）或调用window.refresh（）直接进行物理屏幕更新。
尝试此片段：

#write text
stdscr.addstr(0, 0, 'test')

#loop program so the terminal does not close
while 1:
    c = stdscr.getch()
    key = curses.keyname(c)
    if key == b'q':
        break
    else:
        stdscr.addstr(1, 0, repr(key))

curses.endwin()

You have to refresh the screen. Curses does a physical screen update when you ask for input, e.g. with window.getch() or call window.refresh() directly.
Try this snippet:

#write text
stdscr.addstr(0, 0, 'test')

#loop program so the terminal does not close
while 1:
    c = stdscr.getch()
    key = curses.keyname(c)
    if key == b'q':
        break
    else:
        stdscr.addstr(1, 0, repr(key))

curses.endwin()
