我非常非常困惑...

基本上是试图声明一个指向curses窗口的全局变量,以便我可以使用调试命令,但是它抱怨AttributeError: 'NoneType' object has no attribute 'addstr'这意味着未设置它?请帮忙!

wDebug = None

def start(stdscr):
    curses.nocbreak()
    curses.echo()
    screenSize = stdscr.getmaxyx()

    wDebug = curses.newwin(5, screenSize[1], 0, 0);

    curses.init_pair(1, curses.COLOR_WHITE, curses.COLOR_BLUE)

    wDebug.bkgd(curses.color_pair(1))
    wDebug.refresh()

    /* Snip */

    awaitInput(wInput)

    while 1: pass

def awaitInput(window):
  while 1:
    msg = /* Snip */
    sendMessage(msg)

def sendMessage(msg):
  /* Snip */
  debug("Send message")

def debug(msg):
  wDebug.addstr(msg + "\n")
  wDebug.refresh()


非常感谢您的宝贵时间,

最佳答案

您需要使用global statement

wDebug = None

def start(stdscr):
    global wDebug
    #...
    wDebug = curses.newwin(5, screenSize[1], 0, 0);


从文档中:


  如果没有global,将不可能分配给全局变量
