How to keep track of mouse events and position using selenium and javascript in python?

I am working to get the element details while clicking on that element inside the selenium web driver in python by executing a javascript function on the page.

But it is not working as I expected, even I have used the async method to get the element details from javascript to python. But I still can't able to get the element details in serverside python code.

Please provide a better solution for this case.

sample code

@asyncio.coroutine
def mouseevent(driver):
            while true:
                mouse =driver.execute_script(''' 
                    var x= onclick = function(e){
                        return e.target;
                    }
                ''')
                print(mouse)

driver=webdriver.Chrome(Chrome)

driver.implicitly_wait(30)
driver.maximize_window()
driver.get("https://www.google.com/")


loop = asyncio.get_event_loop()

tasks = [
    asyncio.ensure_future(mouseevent(driver))]
loop.run_until_complete(asyncio.wait(tasks))
loop.close()

Thanks in Advance.

Maybe there is better method but this code works for me.

First I create variable window.x with default value at start so I can check its value all the time - even if I don't click any element.

driver.execute_script('window.x = null;')

Later I assign to body function which will be executed when I click body - it will assign value to window.x 

driver.execute_script('document.body.addEventListener("click", function(e) { window.x = e.target;})')

And in loop I only check value in this variable. 

while True:
    print(driver.execute_script('return window.x'))
    time.sleep(0.5)

It would need to check if value was changed between loop or it should run function which copy value from window.x to ie. window.y, next it clearn window.x and it returns window.y - this way it will get value only once.

while True:
    print(driver.execute_script('window.y = window.x; window.x = null; return window.y'))
    time.sleep(0.5)

import selenium.webdriver
import time

url = 'https://stackoverflow.com'
driver = selenium.webdriver.Firefox()
driver.get(url)

driver.execute_script('window.x = null;')

driver.execute_script('document.body.addEventListener("click", function(e) { window.x = e.target;})')

while True:
    print(driver.execute_script('window.y = window.x; window.x = null; return window.y'))
    time.sleep(0.5)

EDIT: I found answers which should better resolve problem: Javascript - Track mouse position
