Wait until loader disappears python selenium

Answer 1

Use expected condition : invisibility_of_element_located

This works fine for me.

from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait


WebDriverWait(driver, timeout).until(EC.invisibility_of_element_located((By.ID, "loader-mid")))
