python 监视和控制鼠标键盘的输入（使用pynput 而非pyhook）

百度上搜到的文章大多基于pyhook， pip不能直接安装，托管在sourceForge上的代码仓库也找不到。

google上发现可以使用pynput，貌似控制更为简单，而且可以直接使用pip安装

示例代码如下

from pynput.mouse import Button, Controller
mouse = Controller()
# Read pointer position
print('The current pointer position is {0}'.format(
    mouse.position))
# Set pointer position
mouse.position = (10, 20)
print('Now we have moved it to {0}'.format(
    mouse.position))
# Move pointer relative to current position
mouse.move(5, -5)
# Press and release
mouse.press(Button.left)
mouse.release(Button.left)
# Double click; this is different from pressing and releasing
# twice on Mac OSX
mouse.click(Button.left, 2)
# Scroll two steps down
mouse.scroll(0, 2)
