Python simulate keydown
This code should get you started. ctypes is used heavily. At the bottom, you will see example code.

If you're using Python for Windows then there's a very good chance that you have the win32api module, which handles hooking into the API for you...
import win32apiimport win32conwin32api.keybd_event(win32con.SHIFT_PRESSED, 0,win32con.KEYEVENTF_EXTENDEDKEY, 0)Does that help? (p.s. you should install IPython if, at all possible, it's massively helpful for experimenting)
I know that this question is really old, but I found a nice library: PyUserInput.I am not sure how to download it in windows(I haven't downloaded libraries for windows for a long time). In Linux is easy just download pip(if you haven't):sudo apt-get install pip and then sudo pip install pyuserinput.And then the code is realy simple:
#imports the libraryfrom pykeyboard import PyKeyboard#import the sleep functionfrom time import sleep#initialize the keyboard simulatorkeyboard = PyKeyboard()#presses the keykeyboard.press_key('x')#waits five seconds before releasing the keysleep(5)#releases the keykeyboard.release_key('x')
