Question

我想创建一个可以在后台运行的python脚本，但是当mouseevent或keyevent发生时打印文本。是否有任何库/内置功能来实现这一目标？或者我可以调用任何系统命令来获取此信息？成为根本不是问题。

我猜你可能会对evdev使用python绑定：http://packages.python.org/evdev/index.html。在教程中，他们给出了键盘的示例，但对于鼠标事件应该类似：

>>> from evdev import InputDevice, categorize, ecodes
>>> from select import select
>>> dev = InputDevice('/dev/input/event1')

>>> print(dev)
device /dev/input/event1, name "Dell Dell USB Keyboard", phys "usb-0000:00:12.1-2/input0"

>>> while True:
...    r,w,x = select([dev], [], [])
...    for event in dev.read():
...        if event.type == ecodes.EV_KEY:
...            print(categorize(event))
... # hitting a and holding space
key event at 1337016188.396030, 30 (KEY_A), down
key event at 1337016188.492033, 30 (KEY_A), up
key event at 1337016189.772129, 57 (KEY_SPACE), down
key event at 1337016190.275396, 57 (KEY_SPACE), hold
key event at 1337016190.284160, 57 (KEY_SPACE), up

请查看pynput，例如：

from pynput.keyboard import Key, Listener
#defining function to print when key is pressed
def on_press(key):
  print('{0} pressed'.format(
    key))
#defining function to print when key is released
def on_release(key):
  print('{0} release'.format(
    key))
  if key == Key.esc:
    # Stop listener
    return False

# Collect events until released
with Listener(
    on_press=on_press,
    on_release=on_release) as listener:
    listener.join()
