Generating Mouse-Keyboard combination events in python

I want to be able to do a combination of keypresses and mouseclicks simultaneously, as in for example Control+LeftClick

At the moment I am able to do Control and then a left click with the following code:

import win32com, win32api, win32con
def CopyBox( x, y):

    wsh = win32com.client.Dispatch("WScript.Shell")
    wsh.SendKeys("^")
    win32api.SetCursorPos((x,y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, x, y, 0, 0)

What this does is press control on the keyboard, then it clicks. I need it to keep the controll pressed longer and return while it's still pressed to continue running the code. Is there a maybe lower level way of saying press the key and then later in the code tell it to lift up the key such as like what the mouse is doing?

to press control:

win32api.keybd_event(win32con.VK_CONTROL, 0, win32con.KEYEVENTF_EXTENDEDKEY, 0)

to release it:

win32api.keybd_event(win32con.VK_CONTROL, 0, win32con.KEYEVENTF_EXTENDEDKEY | win32con.KEYEVENTF_KEYUP, 0)

so your code will look like this:

import win32api, win32con
def CopyBox(x, y):
    time.sleep(.2)
    win32api.keybd_event(win32con.VK_CONTROL, 0, win32con.KEYEVENTF_EXTENDEDKEY, 0)
    win32api.SetCursorPos((x,y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, x, y, 0, 0)
    win32api.keybd_event(win32con.VK_CONTROL, 0, win32con.KEYEVENTF_KEYUP, 0)
