Answer 2

使用Tkinter的，你可以做以下的....我發現它在網絡上

# KeyLogger_tk2.py 
# show a character key when pressed without using Enter key 
# hide the Tkinter GUI window, only console shows 

try: 
    # Python2 
    import Tkinter as tk 
except ImportError: 
    # Python3 
    import tkinter as tk 

def key(event): 
"""shows key or tk code for the key""" 
    if event.keysym == 'Escape': 
     root.destroy() 
    if event.char == event.keysym: 
    # normal number and letter characters 
     print('Normal Key %r' % event.char) 
    elif len(event.char) == 1: 
     # charcters like []/.,><#$ also Return and ctrl/key 
     print('Punctuation Key %r (%r)' % (event.keysym, event.char)) 
    else: 
     # f1 to f12, shift keys, caps lock, Home, End, Delete ... 
     print('Special Key %r' % event.keysym) 


root = tk.Tk() 
print("Press a key (Escape key to exit):") 
root.bind_all('<Key>', key) 
# don't show the tk window 
root.withdraw() 
root.mainloop()

這就是你可以用ncurses的做到這一點。與TkInter不同，X11不是必需的。

#! /usr/bin/python 

import curses 

screen = curses.initscr() 
try: 
    curses.noecho() 
    curses.curs_set(0) 
    screen.keypad(1) 
    screen.addstr("Press a key") 
    event = screen.getch() 
finally: 
    curses.endwin() 

if event == curses.KEY_LEFT: 
    print("Left Arrow Key pressed") 
elif event == curses.KEY_RIGHT: 
    print("Right Arrow Key pressed") 
else: 
    print(event)
