python 監視和控制鼠標鍵盤的輸入（使用pynput 而非pyhook）

百度上搜到的文章大多基於pyhook， pip不能直接安裝，托管在sourceForge上的代碼倉庫也找不到。
google上發現可以使用pynput，貌似控制更為簡單，而且可以直接使用pip安裝

示例代碼如下

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)
