Wait until element is not present

Question

I'm using selenium in Python 2.7 and I have this code, but I'm looking for a more efficient way to do this:

while True:
    try:
        element = WebDriverWait(driver, 10).until(
            EC.presence_of_element_located((By.ID, 'button'))
        )   
    except:
        break

Answer 1

 element = WebDriverWait(driver, 10).until(
            EC.invisibility_of_element_located((By.ID, 'button'))

you don't need to use while. it already waits for time that you present in WebDriverWait() function.
