a function to interact with select2 element using Selenium and Python (inspired by https://stackoverflow.com/a/17757761/8504344 and tested on firefox)

select_option_for_select2.py

def select_option_for_select2(driver, id, text=None):
    element = driver.find_element(By.XPATH, '//*[@id="{}"]/following-sibling::*[1]'.format(id))
    element.click()

    if text:
        element = driver.find_element(By.CSS_SELECTOR, "input[type=search]")
        element.send_keys(text)

    try:
        element.send_keys(Keys.ENTER)
    except ElementNotInteractableException as e:
        actions = ActionChains(driver)
        a = actions.move_to_element_with_offset(element, 50, 30)
        a.send_keys(Keys.ENTER)
        a.perform()
