PyAutoGUI lets your Python scripts control the mouse and keyboard to automate interactions with other applications.
To install with pip, run: pip install pyautogui
import pyautogui
screenWidth, screenHeight = pyautogui.size() # Get the size of the primary monitor.
currentMouseX, currentMouseY = pyautogui.position() # Get the XY position of the mouse.
pyautogui.moveTo(100, 150) # Move the mouse to XY coordinates.
pyautogui.click() # Click the mouse.
pyautogui.click(100, 200) # Move the mouse to XY coordinates and click it.
pyautogui.click('button.png') # Find where button.png appears on the screen and click it.
pyautogui.move(0, 10) # Move mouse 10 pixels down from its current position.
pyautogui.doubleClick() # Double click the mouse.
pyautogui.moveTo(500, 500, duration=2, tween=pyautogui.easeInOutQuad) # Use tweening/easing function to move mouse over 2 seconds.
pyautogui.write('Hello world!', interval=0.25) # type with quarter-second pause in between each key
pyautogui.press('esc') # Press the Esc key. All key names are in pyautogui.KEY_NAMES
pyautogui.keyDown('shift') # Press the Shift key down and hold it.
pyautogui.press(['left', 'left', 'left', 'left']) # Press the left arrow key 4 times.
pyautogui.keyUp('shift') # Let go of the Shift key.
pyautogui.hotkey('ctrl', 'c') # Press the Ctrl-C hotkey combination.
pyautogui.alert('This is the message to display.') # Make an alert box appear and pause the program until OK is clicked.pip install redis

request 使用的是 urllib3，继承了urllib2的所有特性。Requests支持HTTP连接保持和连接池，支持使用cookie保持会话，支持文件上传，支持自动确定响应内容的编码，支持国际化的 URL 和 POST 数据自动编码。
There are many libraries to make an HTTP request in Python, which are httplib, urllib, httplib2, treq, etc., but requests is the one of the best with cool features.
