如何在linux上的后台使用python捕获mouseevents和keyevent

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.

我想,你可以使用python绑定evdev: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
