Controlling mouse with Python

Questions:

How does one control the mouse cursor in Python, i.e. move it to certain position and click, under Windows?

Answers:

Tested on WinXP, Python 2.6 after installing pywin32 (pywin32-214.win32-py2.6.exe in my case):

import win32api, win32con
def click(x,y):
    win32api.SetCursorPos((x,y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,x,y,0,0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0)
click(10,10)

Questions:
Answers:

You can use win32api or ctypes module to use win32 apis for controlling mouse or any gui

Here is a fun example to control mouse using win32api:

import win32api
import time
import math

for i in range(500):
    x = int(500+math.sin(math.pi*i/100)*500)
    y = int(500+math.cos(i)*100)
    win32api.SetCursorPos((x,y))
    time.sleep(.01)

A click using ctypes:

import ctypes

# see http://msdn.microsoft.com/en-us/library/ms646260(VS.85).aspx for details
ctypes.windll.user32.SetCursorPos(100, 20)
ctypes.windll.user32.mouse_event(2, 0, 0, 0,0) # left down
ctypes.windll.user32.mouse_event(4, 0, 0, 0,0) # left up

Try with the PyAutoGUI module. It’s multiplatform.

pip install pyautogui

And so:

import pyautogui
pyautogui.click(100, 100)

It also has other features:

import pyautogui
pyautogui.moveTo(100, 150)
pyautogui.moveRel(0, 10)  # move mouse 10 pixels down
pyautogui.dragTo(100, 150)
pyautogui.dragRel(0, 10)  # drag mouse 10 pixels down

This is much easier than going through all the win32con stuff.

Check out the cross platform PyMouse: https://github.com/pepijndevos/PyMouse/

Another option is to use the cross-platform AutoPy package. This package has two different options for moving the mouse:

This code snippet will instantly move the cursor to position (200,200):

import autopy
autopy.mouse.move(200,200)

If you instead want the cursor to visibly move across the screen to a given location, you can use the smooth_move command:

import autopy
autopy.mouse.smooth_move(200,200)

from Xlib import X, display
d = display.Display()
s = d.screen()
root = s.root
root.warp_pointer(300,300)

Quick and dirty function that’ll left click wherever clicks times on Windows 7 using the ctypes library. No downloads required.

import ctypes

SetCursorPos = ctypes.windll.user32.SetCursorPos
mouse_event = ctypes.windll.user32.mouse_event

def left_click(x, y, clicks=1):
  SetCursorPos(x, y)
  for i in xrange(clicks):
   mouse_event(2, 0, 0, 0, 0)
   mouse_event(4, 0, 0, 0, 0)

left_click(200, 200) #left clicks at 200, 200 on your screen. Was able to send 10k clicks instantly.
