Python & Selenium - how do I find all element IDs on a page?

Question

I know that I can use methods such as:

find_elements_by_tag_name()
find_elements_by_id()
find_elements_by_css_selector()
find_elements_by_xpath()

Answer 1

from selenium import webdriver

driver = webdriver.Firefox()
driver.get('http://google.com')

ids = driver.find_elements_by_xpath('//*[@id]')
for ii in ids:
    #print ii.tag_name
    print ii.get_attribute('id')    # id name as string
