如何在Python中檢測curses ALT +組合鍵

Question

這裏是python的新手，並使用curses導入。我想檢測像ALT + F和類似的組合鍵。目前，我使用getch()接收密鑰，然後將其打印在curses窗口中。該值不會更改爲F或ALT + F。如何檢測ALT組合鍵？

import curses 

def Main(screen): 
    foo = 0 
    while foo == 0: 
     ch = screen.getch() 
     screen.addstr (5, 5, str(ch), curses.A_REVERSE) 
     screen.refresh() 
     if ch == ord('q'): 
     foo = 1 

curses.wrapper(Main)

試試這個：

import curses 

def Main(screen): 
    while True: 
     ch = screen.getch() 
     if ch == ord('q'): 
     break 
     elif ch == 27: # ALT was pressed 
     screen.nodelay(True) 
     ch2 = screen.getch() # get the key pressed after ALT 
     if ch2 == -1: 
      break 
     else: 
      screen.addstr(5, 5, 'ALT+'+str(ch2)) 
      screen.refresh() 
     screen.nodelay(False) 

curses.wrapper(Main)
