在这个程序的早期版本中，echo() 工作正常，但在一些重写后停止工作。我能想到的唯一可能相关的是主窗口（self.screen）现在是一个pad而不是stdscr。
其他一切都像以前应该做的那样工作；当我在一个选择上按回车键时，我可以输入一个字符串，当我完成后，字符串就在我输入它的地方。它只是在我键入或粘贴时不会回显它，并且在 getstr() 完成之前我看不到它。我不明白为什么。在我看来，这一切都应该像 echo()/noecho() 一样简单。
我错过了什么还是这是一个错误？
（我知道这段代码不符合 pep8。我最终会解决这个问题）
在旧版本中工作！：
if q == ord("\n"):
if selection >= 0:
target_value = values[selection][0]
screen.timeout(-1)
curs_set(1)
curs_pos = values[selection][1]
screen.move(curs_pos[0], curs_pos[1])
screen.clrtoeol()
echo()
if selection == 0:
self.TargetDict[Target].Name = screen.getstr()
if selection == 1:
new_ip = screen.getstr()
if selection == 2:
self.TargetDict[Target].CPE = screen.getstr()
if selection == 3:
self.TargetDict[Target].Inc = screen.getstr()
if selection == 4:
self.TargetDict[Target].Inst_ID = screen.getstr()
if selection == 5:
self.TargetDict[Target].Span_ID = screen.getstr()
noecho()
curs_set(0)
screen.timeout(300)
self.screen.addstr(0,0, str(counter))
counter += 1
self.screen.refresh()
不工作！：

target_value = values[selection][0]
self.screen.timeout(-1)
curs_set(1)
self.screen.move(values[selection][1][0], values[selection][1][1])

curses.echo()
self.screen.refresh(0, 0, 0, 0, self.y_max-1, self.x_max-1)
if selection == 0:
self.TargetDict[Target].Name = self.screen.getstr()
if selection == 1:
#not used. Can't change target address
new_ip = self.screen.getstr()

self.screen.timeout(300)
self.update_details(Target, option)
self.screen.refresh(0, 0, 0, 0, self.y_max-1, self.x_max-1)
这是整个功能
