为什么当我运行此代码时box.getch()返回错误的值，而当我更改box.getch()为screen.getch()它时返回正确的值？我一直在网上寻找，没有人说getch()只适用于屏幕。如果您按下其中一个箭头，它将返回 27，这是 ESC 的字符。（此代码应打印字符，直到用户按 ESC ...）

import curses
screen = curses.initscr()
curses.noecho()
curses.cbreak()
curses.start_color()
screen.keypad( 1 )
curses.init_pair(1,curses.COLOR_BLACK, curses.COLOR_CYAN)
highlightText = curses.color_pair( 1 )
normalText = curses.A_NORMAL
screen.border( 0 )
curses.curs_set( 0 )
box = curses.newwin( 22, 64, 1, 1 )
box.box()
box.addstr( 14, 3, "YOU HAVE PRESSED: ")

screen.refresh()
box.refresh()

x = box.getch()
while x != 27:
    box.erase()
    box.addstr( 14, 3, "YOU HAVE PRESSED: " + str(x) )
    screen.border( 0 )
    box.border( 0 )
    screen.refresh()
    box.refresh()
    x = box.getch()

curses.endwin()
exit()

#!/usr/bin/python3

screen.border ( 0                    )
e             = curses.noecho(       )
e             = curses.cbreak(       )
e             = curses.start_color(  )

normalText    = curses.A_NORMAL
box           = curses.newwin(  20, 60, 1, 1 )
box.keypad( 1 )
box.box(      )

try:
  while x != 50 :            #     27  ESC
    box.erase(       )
    cc="WTF?"
    try:     cc=str(chr(x))
    except:  cc="ERR"
    box.addstr( 8, 8, "key 2 to quit, you pressed" + str(x) + "  '" + cc + "'" )
    screen.border( 0 )
    box.border(    0 )
    x = box.getch(   )
except : print("oh my!")
finally: curses.endwin() # avoids messed up console!

答案（请参阅python curses 中的带有刷新的错误）是添加box.keypad(1). 有几行是不必要的 - 这些在示例中被标记：

    导入诅咒
    屏幕 = curses.initscr()
    诅咒.noecho()
    诅咒.cbreak()
    curses.start_color()
    screen.keypad(1) # 删除这一行
    curses.init_pair(1,curses.COLOR_BLACK, curses.COLOR_CYAN)
    highlightText = curses.color_pair(1)
    normalText = curses.A_NORMAL
    screen.border(0)
    诅咒.curs_set(0)
    盒子 = curses.newwin(22, 64, 1, 1)
    box.keypad(1)
    盒子.盒子（）
    box.addstr(14, 3, "你已经按下:")

    screen.refresh() # 删除这一行
    box.refresh()

    x = box.getch()
    而 x != 27:
        box.erase()
        box.addstr( 14, 3, "你已经按下:" + str(x) )
        screen.border(0)
        box.border(0)
        screen.refresh() # 删除这一行
        box.refresh() # 删除这一行
        x = box.getch()

    诅咒.endwin()
    出口（）
