Passing functions and image paths into another function in Python

Question

I've build what turned out to be quite an extensive script and now I'm trying simplify it. myFunct() repeats most often:

import time
import pyautogui

(...)

img1 = 'images/img1.png'
img2 = 'images/img2.png'

def doSmth1():
    # do stuff

def doSmth2():
    # do stuff

def myFunct():
        while 1:
            if pyautogui.locateOnScreen(img, confidence = 0.9) != None:
                doSmth()
                break
            else:
                time.sleep(0.5)

How can I pass img1 or img2 as img and doSmth1() or doSmth2() as doSmth() into the myFunct()?
